In our era of far-developed com puter technology, many opening variations and whole systems have been re-evaluated. With the help of powerful computers many lines have been analysed deeply, resulting in the discovery of not only new horizons but also new problems. For example, one of the main problems for the I .e4-player always used to be the Sicilian Defence, which became too dangerous in the main lines. The winner would be the player whose computer's calculations were deeper and more accurate . As a result, the game became of secondary importance. That is why many strong players be came unhappy and started to search for new ways. I was no ex ception . During the search for new ideas for White, I stumbled upon the repertoire of Uzbek Grandmas-

ter S aidali Yuldashev and was amazed at his score against the Sicilian. The most interesting for me was the line that begins with I .e4 c5 2.tlJc3 tlJc6 3 .�b5 g6 4.�c6. Therefore, I started to analyse it carefully, and I was impressed by the results ! Fi rst - The Strategic Poi nt The idea of the move 3 .�b5 is very simple: White prepares to exchange on c6 and spoil his op ponent's pawn structure similar to the Rossolimo Variation ( l .e4 c5 2 . tlJ f3 tlJc6 3 .�b5 ) , but with one important difference : the king's knight doesn ' t block the f-pawn , which can easily be pushed to f4. Aside from the ob vious space grabbing, this pawn takes control of the important central square e5 and it can also signal the attack - f4-f5 ! The great Jose Raul Capablanca taught us to put our own pawns on the exchanged bishop 's squares, thus hinderi ng the activ ity of the opponent's bishop. Thus, after l .e4 c5 2.tlJc3 tlJc6 3 . �b5 g6 4.�c6 bc6 White can immediately follow Capa blanca's rule by j ust moving his d-pawn to d3. One of White ' s possible plans w i l l now b e to play on the l ight squares: b2-b3 , tlJa4, c2-c4. Usually this is possi ble after the central pawns have been fixed with . . . d6-d5 and e4-e5 . This change in the pawn structure favours White because

Saidall Yuldashev

the c5-pawn becomes a conve nient target to fix and attack. Thus , White ' s pawn structure in the centre is very solid and it is not easy to find an active plan for B lack. Thi s is one of the main advantages of the system, as well as B lack ' s light-squared bi shop, which is not only boxed in by its own pawns, but also se verely l imited by the enemy pawns located on the light squares. I n that case, it i s normal that B lack should forget about attacking and just tries to defend h i s weak and doubled pawns c5 and c6. Do You Want to Atta ck? Initially, the idea behind the ex change on c6 was to play against the doubled pawns and Black's bad l ight-squared bishop. How ever, what should a white player

do if he gets bored of attacking his opponent's weaknesses and wants to get at his king? The 3 .Ab5 system allows you to vary your plans ! One of the ma jor plans is to move your queen to h4 as soon as possible, with the idea of f4-f5 and then Ah6 and tl:lg5 . This was perfectly demonstrated in the game Yuldashev-An Nguyen Dung . This plan was so unpleasant for Black that strong players de cided to develop the king's knight to h6 with the idea to de lay the attack with . . . t7-f5 . How ever, then White should put the pawn on e5 and the bi shop begins to suffer on g7 ! (see the games Yuldashev-Fier and Tivi akov-Maze) The Various Squares for the King's Knight In my opinion, the worst square for the g8-knight is e7. This is the least popular move because one more pawn has to be put on a light square ( . . . e7-e6), which makes the light-squared bishop on c8 more passive, as in the game Neumann-Angelov, Inter net blitz 2004, which went l . e4 c5 2 .tl:lc3 tl:lc6 3 . f4 d6 4.�b5 e6 5 .i.c6 bc6 6.d3 tl:le7 7.tl:lf3 g6 8 .0-0 i.g7 9.tl:la4 0-0 1 0. l:tb l �a6 l l .b3 i.b5 1 2 .tl:lb2 d5 l 3 .c4 ! .ia6 l 4.tl:la4 �d4 l 5 .@h l f5 l 6 .e5

White has a large advantage and the bishop on a6 is out of play. The development to f6 looks more thematic . After the moves l .e4 c5 2.tl:lc3 tl:lc6 3 .Ab5 g6 4 . .tc6 bc6 5 .d3 i.g7 6 . f4 d6 7 . tl:lf3 l:tb8 8 .0-0

the question i s : where to develop the knight? f6 looks quite logi cal. But this has one notable drawback: it will be difficult for Black to prevent White ' s initia tive on the kingside associ ated with f4-f5 : 8 . . . tl:lf6 9 .'ii' e l ! Ag4 I O.tl:ld2 ! ? (White doesn ' t want to exchange B lack's bad bishop) 10 . . . 0-0 l l ..,h4 �d7 1 2. tl:lf3 tl:le8 1 3 . f5 , and White had a serious initiative in Z.Jovanovic-Bosnj ak, Bosn j aci 20 1 2 .

The game Hebden-Umesh, Glas gow Open 1 995, went 7 . . . tl:lf6 (instead of 7 . . . l:tb8) 8 .0-0 0-0 9 .'ii' e 1 ! l:.b8 I O.b3 ! ? 'it'd? l l .Ad2 tl:le8 1 2 .'ii' h 4 ! tl:lc7 1 3 . l:tae l i.a6 1 4. f5 !

And White ' s attack is running smoothly. The most popular square for the knight is h6. It may create some trouble for White ' s kingside for mation and does not require the move . . . e7-e6. But the knight is too far from the centre. The basic plan for White is typical: he puts his pawns on light squares and prepares to attack the doubled pawns. The standard answer . . . t7-f5 should be met by e4-e5, boxing in Black's dark-squared bishop and then weakening B lack's pawn structure in the centre, as in the game Tiviakov Maze, Montreal 2009, which continued (after 7 .tLlf3 ) 7 . . . tl:lh6 8 .0-0 0-0 9.�h l f5 I O. es tl:lf7 l l .'ft'e2 'flic7 1 2 . l:.e l tl:ld8 1 3 .i.d2 ! tl:le6 1 4 .'ii' f2 (taking aim at the pawn on c 5 ) 1 4 . . . l:td8 1 5 .tl:la4 ! tl:lf8 1 6.b3 !

Kasimdzhanov-Afek). It is im portant to know that it is good for White to exchange the dark squared bishops.

In the game Tiviakov-Di Paolo, Solsona 2003, Black tried to es cape with 6 . . . c4, which led to a pawn-down endgame. The game Jones-Abhi shek is a great dem onstration of White's attacking opportunities in the 4 . . . dc6 vari ation.

The Other Recaptu re

4 dc6 leads to another type of positions where the point for White is to move �e3 , 'ti'd2 and f2-f4 in answer to . . . e7-e5 . Then White should try to make use of his better pawn structure (see

Concl usion The system with 3 . �b5 is a very venomous weapon for White. Black must play very accurately to avoid finding himself in a hopeless position.

One of the main reasons for the popularity for the Rossol imo i s that it forces B l ack o u t o f his fa vourite pos itions ( i . e . his Open Sici lian of choice) and, due to the openi ng's flexibil ity, gives White a degree of control over the nature of the ensuing middlegame . Of course , one can go down the paths of the theoretically trendy 3 . . . e6, but it's nice to throw your opponent out of their comfort zone by forc ing them away from typical Rossolimo positions. I ndeed, you probably haven ' t seen the position after 4 . . . �d6 before today ! While Georgia's top pl ayer Baadur Jobava wasn ' t the first person t o employ this system, he i s the fi rst strong grandmaster to play it more than once and a few other grandmasters have followed his lead since.

52

Of course, in the main lines of the Rossolimo White often ex changes on c6, but here that plays into Black's hands due to his strong-point on e5 (as my notes to Novikov-Konovalov illustrate) . In this game I also demonstrate why White's alter natives to 5 .c3 are not dangerous for Black. Jobava's Praxis White's only serious try for an advantage is to break open the centre with 5 .c 3 tl.lge7 6.d4, and after 6 . . . cd4 7 .cd4 ed4 8 .tl.ld4 a6 we reach the first key position : where does White ' s light squared bishop belong?

In Jobava's first game, Matinian opted for 9 .�e2 0-0 1 O.tl.lc3, after which Jobava revealed his idea: 1 0 . . . �e5 1 l .�e3 d5 ! , blowing open the centre and directly vying for equality. In the game White's 1 2.tl.lc6 didn ' t give him anything, although Jobava's eventual vic tory was not without errors from both sides.

Baadur Jobava

Jobava's second opponent, B artel, tried l 2 .ed5 instead, but this resulted i n an equal and fairly dour endgame. Only i n the Main Game of the Survey (Solak-Jobava) did White achieve an advantage, placing the bishop on the a2-g8 diagonal with 9.�c4 ! (where it puts paid to any . . . d5 ideas). Jobava held a draw only by the skin of his teeth . Fellow Australian, grandmaster David Smerdon, has already done a solid analysis of Jobava's games in this line on ChessPublishing but I ' ve ana lysed these games in more detail for this Survey. I share his con clusion that Black can ' t prove equality after 9.�c4 - though Black is fairly solid i n these slightly worse positions. The main practical disadvantage of

Survey SI 3 1 . 1 this line for B lack is that even when he equalizes, the resulting positions don ' t offer many chances to win. Is Correspondence Play Ahead of the Times? Black has tried a few moves other than 5 . . . tLlge7, but the main move in correspondence chess has been 5 . . . a6, trying to provoke 6.�c6 (which is a fairly comfort able version of the Exchange Ruy Lopez for B lack, as Sirotkin-Kireev, corr. 20 1 2, shows). After the more natural 6.�a4 b5 7 . �b3 �b7

the structure is much more like a Ruy Lopez than a Sicilian, and 8 .d4 ed4 ! 9 . cd4 c4 l 0.�c2 tLlb4 gave B lack the bi shop pair and counterplay against White ' s im posing centre i n Hansen-Rogos, email 20 I O, but 8 .d3 ! is much more problematic, as B l ack ' s bi shops both look o u t of place i n t h i s pawn structure. Then 8 . . . tLlf6 9 . tLl h4 led to a resound ing win for White i n the high level correspondence game Pri makov-Timko. Maybe B l ack has to play 9 . . . �f8 , but if B lack has to make this counter-devel oping move then the whole line . feels a bit untrustworthy. I t ' s worth noti ng though that the computers slightly overestimate White ' s chances in the typical middlegames - if B lack i s able to exchange White ' s l ight squared bi shop and queen ' s knight he almost always equal izes, as then White won ' t be able to make use of the hole on d5 .

Conclusion In modem opening theory there are several forgotten or little known systems that are fully playable; one only needs to flick through a Yearbook to find evi dence of thi s . However I think this 4 . . . �d6 system will soon fade into obscurity again - not because White has a slight ad vantage based on the Solak Jobava and Primakov-Timko games, but because of the following practical dilemma: against a weaker player it will be hard to win the very dry posi tions which often occur in the main line, but a higher-rated player will try to grind down your robust position all day ! Therefore I recommend using this system only as a surprise weapon for trying to make a draw. Of course, you can always wait until 4 . . . �d6 becomes 'old his tory ' and only then spring it on an unsuspecting opponent !

LI Chao

This variation occurred twice last year in games of the Chinese grandmaster Li Chao . Compared with the better known main line of the De La Bourdonnais Varia tion (7 . . . 'iff6), in the endgame after the exchange of queens the knight will probably be better placed at e7 than at f6. In addi tion, 8.'ifc7, which is dangerous in the main line, is not so here on account of 8 . . . d5 ! . And after the most logical move 8 .'ii' d l the black knight comes out to f6, which probably should also be regarded as a virtue . Two Options In the starting position White has two options. He can retreat his queen or fight for an advantage in the endgame.

1 0. �e2 Another logical looking plan for White is to force .. �.e6 and then, after invading with lLlc3-d5 , ob tain a position with two bishops against two knights : I O.�g5 �e6 l I .lLld5 �d5 l 2 .ed5 . But in Nasanjargal-Kriebel, Maribor 20 1 2, B lack demonstrated an in teresting plan of counterplay on the queenside: l 2 ... lLlb8 1 3 .�e2 0-0 1 4.0-0 lLlbd7 1 5 .c4 l:Z.fb8 ! ?. 1 0 ... 0-0 1 1 . �e3

1 1 ... bS The idea of developing the bishop on b7 is a new plan. The older plan 1 1 . . . �e6 occurred in Bej tovic-Zwardon , M arianske Lazne 20 1 3 , but it allows White to gain a slight advantage with out particular problems. 1 2.0-0 � b7 1 3.a4 It would be interesting to test 1 3 .lLld5 ! , which has not yet oc curred. 1 3 ... tt:ld4! After simplification White re tained some initiative in Berg-Li, Malmo 20 1 2, but the limited ma terial allowed Black to solve his problems without much diffi culty. Adva ntage in the Endgame White ' s second option is to try and exploit the advantage of the

Hamdani,Rudin Li Chao Zaozhuang 201 2 (7)

As was shown by the further development of events in Carlsen-Radj abov, Astana 20 1 2, White has some initiative, of course, but to transform it into real winning chances is ex- . tremely difficult. Instead of the immediate break in the centre, 9 . . . tl:ib4 ! ?, which occurred in Kozirev-Perezolov, Cheliabinsk 2008, is of interest.

Conclusion Of course, it would be wrong to assert that after 7 . . . fl/e7 Black has equalizing counterplay in all variations. After 8.fl/d l White can count on a minimal advantage, and after the ex change of queens he retains some initiative. But i n the first case B l ack has a fairly clear plan of counterplay, and i n the end game the drawi n g tendencies are really too strong. But the main thing is that this line with 7 . . . f!/e7 has two serious v i rtues . Firstly, it can b e quickly pre pared, si nce the opponent's op tions are very limited . And secondly, it is very probable that the variation with 7 . . . fl/e7 will come as a total surprise to your opponent. So good luck !

kingside. Anyway, the move 'i!i'a4 is still available - it can be combined with h2-h4 and h4-h5 . Let's take a look at Black's pos sible replies. A) The h-Pawn Push

In my opinion, 1 0 . . . h5 does not help Black to equalize. It just stops h4-h5, but Black's h-pawn will not be easy to protect (see game Mousa-Tork). B ) The Counterattack

1 0 . . . a6 is a playable l ine in which White can take the initiative with l l .h5 ! (see Borm-Kuijf). In this line Black may easily find him self in a slightly worse endgame (De Dovitiis-Gonzalez) .

Some months ago I did some research on a positional line against the Sveshnikov Varia tion. I remembered that 7.tl:id5 , followed by 9.c3, was a reliable recipe: 6.tll db5 d6 7.tl:id5 tl:id5 8.ed5 tl:ie7 (8 . . . tl:ib8 is viewed as the main line nowadays) 9.c3 and now I examined 9 ... tl:ig6 the alternatives are 9 . . .f5 ( 1 0.'it'a4 @f7) and 9 . . . tl:if5 . I was sure that 1 0.'it'a4 was the best move, but my personal chess database showed an old game of mine with a remarkable move : 10 h4 ! ?. What is the main idea here? First, to disturb the knight on g6, sec ond, to squeeze Black on the 56

C) The Knight Journey I O . . . �e7 is the most common

move by B lack. In most cases White replies with I l .h5 , and now we reach a key moment for Black:

C l ) l 1 . . .tll f8 : The black knight retreats in order to return

via d7 and c5. Now White has several options : 1 2.c4 (see Pletanek-Kubikova) ; 1 2.a4 (see Meister-Korpics) or 1 2.�e3 (see Kl undt-Sandner). C2) l l . . . . tl:ih4.

The knight can escape to f5 , but I prefer to have a pawn on that square later on (see games Rudolf-Dobrogost and Roa Alonso-Caruana).

Survey SI 35. 5 Conclusion

There is little material about this line (only 1 1 games), but it is clear that the move 9 ... tbg6 is not enough to equalize, so it must be worse than the alternatives. According to the statistics, 1 0.h4 ! ? is j ust as strong as

l 0.'t!fa4 (both moves score about 77% ). The best option for Black is l 0 . . . �e7, unless he wants to play the slightly inferior end game after I O . . a6. In my opinion l O . . . �e7 l l .h5 llJf8 is the best way to rearrange the pieces (especially transfer-

ring the knight via f8 and d7 to c5), although it will not be easy to equalize. The line l l . . . llJh4 looks more active, but in this case Black's knight does not have a safe place anywhere, and it also obstructs the f-pawn after a future retreat to f5 .

The younger members of my readership won ' t believe that a man who draws 70 per cent of his games - often pretty boringly ever played anything as sharp as the Sveshnikov, which inciden tally should perhaps be called the Cheliabinsk, for as with so many discoveries there are quite a few forefathers. Roots Gennady limoschenko, for one, told me in Moscow 1 984 - where we were both seconds to 72

Kasparov - that he had the earliest game in this variation he knows about. But IM Tamas Horvath, with whom I wrote two books about the subject in 1 986 and 1 992, went further: he showed me the original score sheet of a game played and won before Gennady ever played it. Later on, even the good Arthur Jussupow played this hair-raising variation ! However, it seems that Leonid Shamkovich takes the cake.

And lost against Mikhail Tai . So it goes, as Kurt Vonnegut wrote. A Brilliant Talent

But the truth is that Peter used to play the Benko (beating Van Wely in Groningen 1 996), the Benoni and of course the Griinfeld. That was quite some time ago, however. When we had our first session in 1 993, I saw a brilliant talent comparable only with Kasparov. The boy loved chess, he was diligent and - un like me - had excellent fighting ability. Lovable too. Like a son , of an age similar to my own daughters . Resta rt No wonder he became the youn gest ever grandmaster soon after.

Peter Leko

At that time we had a break that none of us wanted. But in 1 996 we made a restart. Since becom ing a grandmaster he had played many draws, and I told him: 'Lis ten, Peti ! Now you are holding a record. You are the youngest active grandmaster. Charming. Sweet. Playing good chess, too. And they invite you. But don' t you g o and rest o n your laurels. for all records will be broken and then all that matters will be your strength and - of course - your E lo rating. Why do you make so many grey draws?' ' You know, Uncle Bandi,' said the lad, ' Ever since I play the real strong tourna ments, all the sharks want my blood. I had to save my skin.' 'OK ! But now you have 2600 and you play like that too. In order to climb Mount Olympus you must take chances.' And so we - he -

did. As the only serious player to accept that BLACK IS O K ! he beat Topalov, Kramnik, Van Wely

(twice) and others. And, at 2700, he got an invitation to Linares. That was the time when I left him. Without harvesting . Silly, isn't it? But the trouble was : although I respected him more, I found him far l e ss lovable. People ask me about his timidity. What's the reason for it? And I don't know. Somebody with his powerful knowledge, with quite

a lot of experience, and a wealthy man, has no real ambition at the age of 34. B ut I remember the times we had together. And yes, Peter played the S veshnikov 35 times (true, for the last time in 2005) . And he won 8 vs 6 with 2 1 draws. Plus 2 (two) for Black. Is that not OK? The Line

In the previous Survey in Year book 1 05 we dealt with the 7.f4 �b4 system (considered to be the main line), and now I would like to present some interesting options for both sides to deviate from it. Gaining Ground

As I mentioned in the previous Survey, Black has three ways to meet 7.f4: 7 . . . d6, 7 . . . tl:ld4 and 7 . . . �b4. In this series I will ' ignore' 7 ... d6, because it does not fit into the spirit of the Taimanov, but in the latter part of the present Survey I will examine similar Scheveningen-type positions after 8 . . . d6. However, 7 . . . tl:ld4 is gaining ground in today 's tournament practice. 60

This typically Sicilian central exchange comes into consider ation in almost all Taimanov po sitions in which . . . a7-a6 has not been played yet. There are two reasons for this : firstly, it is useful t o eliminate the d4-knight, preventing later jumps to b5 (true, there is still the c3-knight which is able to do the same jump, but it can be pinned or exchanged, too) gaining a sound tempo (by omitting . . . a7-a6) to finish one's develop ment. Secondly, the dark squares have not been weakened yet (as the a7-pawn is still on its starting square), so Black can play . . .b7-b6, with the idea of . . . �f8-c5 (forcing the swap of dark-squared bishops if �e3 has already been played). 8 .�d4 ! ? looks like a blunder in view of 8 ... 'ii' f4, but in fact White has some compensation for the pawn. Yet I don' t think this move can give White an edge (see Khairullin-Bryzgalin, 20 1 1 ).

Boris Grachev

After the 'normal ' 8.'ii' d4 Black has two choices: the original 8 . . . tl:lg4, a motif well-known from the position after 6.�e3 tl:lf6 7.-.d2 ? ! (this seems a move-order inaccuracy; it's better to start with 7.f3) 7 ... tl:ld4 8 .'ii'd4 tl:lg4, and the more fash ionable and natural 8 . . . b6. 8 . . . tl:lg4.

Now White cannot save his bishop (9.�d2 is met by 9 ... 'fi'c5 ,

Survey SI 40. 2

and after the queen swap Black has nothing to fear), and after 9.0-0-0 lll e 3 l 0."ti'e3 a critical position arises: Black has the bishop pair and has traded off two light pieces (decreasing White's attacking potential, of course), but his forces are a bit underdeveloped, and ifhe tries to play the natural I O . . . �c5 1 I .'i'g3 0-0, White still has some pressure after l l .e5 . 8 . b6 is less explored territory. .

whether to play the passive looking 8 . . . d6 or to complicate matters with the unusual 8 . . . a6. Black cannot play in the same way as after 7.f4 �b4 8.lll b 5 'if a5 , as 8 . . . �b4 is wrong here because of the simple 9.a3. Scheveningen

As I pointed out earlier, there is nothing wrong with the Scheve ningen-type set-up 8 . . . d6 either, but it is not to the liking of every Taimanov fan. After 9.lll b 5 "ti'c6 I O."ti'c4 the key move is l 0 . . . l:!.b8 ! , and the game will soon head into ·an equal endgame. 9.e5 lll g4 I O.�g l �c5 looks like the criti cal continuation here. If Black is not happy with the outcome of the main line (7 .ib4), I suggest for him to test both 8 . . . b6 and 8 . . . lll g 4, as there is still room for new dis coveries.

ningen, but such a decision would be quite irrational at this point. The statistics don 't look promising for Black at all . The typical reaction is I 2 . . . lll d4 I 3.�d4 e5 (as usual), but it seems to be insufficient. Strangely enough, the extra tempo gained by Black, which was used to make the king safe, helps White in a forced line ! Therefore, the difference that clearly favours Black (he has saved out on the move . . . "ti'c7, and White has made two moves with his knight: lll b 5 , and then .b ack to d4) must be exploited in some other way, perhaps by 1 l . . .lll d4 1 2.J:id4 b5 (Naer S .Novikov, Sochi 2008).

This move has been recommended by quite a few ChessBase Magazine commen tators, but sadly without any follow-up. . . The natural move 7 ... 'i'a5 (which works well after 7.f4 �b4 8 .lll db5 ) looks suspect here in view of 8.�d2 (I think 8.�f4 gives an edge too). After 7 ... "ti'b8 8.f4 Black faces the same dilemma as after 7.f4:

White plays by the same scheme here as after 7.f4 d6: 9."ti'f3 and 1 0.0-0-0 or �d3, followed by kingside castling. A) Queenside castling: 9."ti'f3 �e7 (9 . . a6 l 0.lll d4 �e7 1 1 .0-0-0 is the same) I 0.0-0-0 a6 l l .lll d4 0-0 l 2.g4 leads to a well-known theoretical position (the first sample game was played back in 1 965 by Mikhail Tai ! ) . It is interesting t o note that i f Black withdraws the queen t o c7 instead of playing 1 1 . . . 0-0, he transposes to a popular Scheve-

If Black plays l 2 . . . "ti'c7 the posi tion looks like an improved ver sion of the 6.�e2 Scheveningen set-ups, where in the original version the white queen finds her way via e l to g3, and the bishop often goes from e2 to d3 (okay, there are plenty of games with �e2-f3 too, which is no longer possible here). But here White managed to put his bishop on d3 at once, gaining an extra tempo. White plays in a very similar way here: 'ii' g3, l:!.ae I (perhaps he in serts 'it>h l too), however, Black is not obliged to choose the lll d 4-b5 plan either. The position 61

remains balanced, but again there is no need to return to c7. Black can profit from the extra tempo by going 1 2 . . . tll d4 I 3.�d4 e5 (Lutz-Nisipeanu, Germany Bundesliga 2005/06) or one move earlier I 1 . . . �d7 (J .Polgar-Pelletier, Biel 2007), although they seem insufficient for full equality. The Critical Line

If the reader studies the games with 8 . . . d6, perhaps he/she will ask the question: is this what I wanted? Is it worth playing 6 ... tll f6 (remember: you wanted to avoid the lines with f3-'G'd2-0-0-0, which are ex tremely popular nowadays ! ) just to end up in another position with opposite-side castling and pawn storms? And for those who are not happy with the Scheve ningen-type position, here is the solution: play 8 . . . a6 instead !

Now 9.e5 (9.tll d4 �b4 leads no where) 9 . . . ab5 I O.ef6 b4 l l .tll b5 b6 (but not l l . . .gf6? l 2.�b6 ! , Morozevich-Andreikin, 2007) leads to a complicated, unusual position, which has not really been tested in practice yet. It is very hard to say whether White has anything here, since we only have a few recent grandmaster games (2007-2009). The engines are quite optimistic for Black, but I advise the reader not to accept all their suggestions indiscrimi nately. The position is quite origi-

nal, so it requires thorough study and understanding. At first sight, White has more possibilities and Black has less clear plans, yet I have been unable to find any promising way for White. Black has a lot of resources in this posi tion, which remained hidden dur ing the recently played games (e.g the manoeuvre . . . tll e 7-f5 or . . . J:ta8-a5 as well). All in all, I would say it is more comfortable to play with white, but Black will be able to keep the balance with correct play. Conclusion

Everything has a price: if you want to avoid a dangerous set-up, you can ' t do this without facing other (less usual) prob lems. In other words, j ust like there is no such thing as a free lunch, there is no such thing as a problem-free opening variation, either.

Recently we studied the latest trends in the variation with 3 .�b5 �d7 (see Yearbook 1 07 ) . Going through the Survey care fully, one could see that winning with black would be extremely difficult or practically impossi ble in certain positions if White does not want to risk and play for a win himself. However, in life choices are necessary, so after 3 .�b5 Black players must have an opportunity to play for a win. The best option for this is 3 ... lLid7 , although objectively speaking this move is not the strongest and sometimes leads Black into inferior positions. In order to win sometimes you have to take a risk ! Please note that the other option, 3 . . . lZJc6, is play able as well , but recently White found possibilities to put B lack under pressure there . Also, there are several forced lines where White can force Black to make a

36

draw (otherwise he would find himself in a bad position). The author of this Survey has been encountering 3 . £b5 in numer ous games duri ng his long ca reer, and recently he has started giving check hi mself, so the ideas and plans of all lines are well-known to me. So let's look at the main ideas and latest developments. After developing the knight to d7 B lack often loses the fight for the centre, since the knight cannot attack it from c6. Usually, White manages to seize control of the centre and get a small develop ment advantage. Black i n turn gets the bishop pair (in most cases the bishop on b5 is ex changed for the knight on d7), gets a solid position and has good long-term chances to neu tralize White's initiative. Mostly very complex positions arise . . . giving the best player chances to win. bam In the diagrammed position White has a choice from three main moves: A) 4.c3, B) 4.d4, C ) 4.0-0. Please note that moves B and C very often lead to the same positions . Variation A The variation 4.c3 is relatively rare compared to the other two moves. However, it is not with out venom, since White keeps his light-squared bishop alive by moving it to c2. In addition,

Veselln Topalov

Black is unable to prevent White from playing d2-d4. So what can Black do?

After 4.c3 lLif6 5 . 'i!fe2 he has two good plans at his di sposal, de pending on where he decides to put his f8-bi shop (e7 or g7). If he develops it to e7, after . . . e7-e5 , then a position with a Ruy Lopez structure arises. Compared to the real Ruy Lopez B lack is several moves ahead in development.

Survey SI 1 . 3-4 Also, his knight is on d7 i nstea
to a position with a ' hedgehog ' structure with chances for both sides) 6 . . . �d7

7 .c4 (it is important to establish control over the centre with thi s move, although 7 .lLic3, a s in Havana Andreikin-Inarkiev, 20 1 3 , can be played as well. In that game Black failed to equal ize, but with correct play, finish ing the development of his pieces, Black should not be worse) 7 ... b5 ( Black has to at tack the white pawn on c4, trying to create counterplay on move 7 or 8, after 7 . . . e5 8 .'ifd3 . If B lack plays passively, as in the game Tiviakov-Anand, Germany Bundesliga 20 1 1 / 1 2, he runs the risk of getting a difficult position after 8 . . . h6 (preventing �c l -g5) 9 . lLic3 llJf6 I 0.0-0 �e7 l l .a4, followed by a4-a5 . So 8 . . . b5 is better. Afterwards White has a choice between 9 . lLi a3 , which will be studied later after 7 . . . b5 , and the new move 9.lLic3 which occurred i n the game Carlsen Anand, Stavanger 20 1 3 , where White got better chances al though Black was able to hold the game and make a draw) 8 .lLia3 (here 8 . lLic3 is interesting, planning to transpose to the game Carlsen-Anand. B ut B lack is not forced to play the weaken ing . . . e7-e5 , he can take on c4 and follow the rapid game A . Muzychuk-Gashimov, War saw 20 1 2, where B lack solved all his opening problems after

8 . . . bc4 9 .'ifc4 e6 I 0.0-0 lLie7 l l .�e3 tl:lg6. But White could clearly have played more strongly and put pressure on B lack with 1 2 .l:ffd l or 1 2 .'ifd4) 8 . . . e5 9.'ifd3 'ifb6 I 0.0-0. This position occurred in two games by the author of thi s Survey against B abula, Dresden 2007 , and Zhigalko, Nakhchivan 20 1 2, from which he scored 1 .5 points, missing a win i n the latter game. It is very difficult to evaluate thi s complex dynamic position cor rectly ; computer engines also fail to do so. Each side has its strengths and weaknesses . Try ing to be as objective as possible, I could say that the position is dynamically balanced, favour ing the stronger player, who usu ally wins. 4 ... lLif6 is a worthy alternative for Black.

Then White can choose between 5 .lLic3 and 5 .0-0. It has long been known that 5 .e5 would be a mis take for White here, since Black gets very good play after 5 . . . 'if a5 6.lLic3 lLie4 7 . �d2 lLic3 8 . �d7 �d7 9 . �c3 'ifa6. The recent high-level Anand game Gelfand, World Championship match 20 1 2, only confirms this. After 5 .lLic3 Black has a good choice from three plans: 5 . . . a6 6 . �d7 lLid7 7 .0-0 e6 (see the game Topalov-Karjakin, Dubai 2002) ; 5 . . . cd4 6.'ifd4 g6 and 6 . . . e5 7 . 'ifd3 h6, followed by . . . �e7, . . . 0-0. Black should al-

37

ways be able to equalize, which is why 5 .0-0 i s more popular these days than other lines. Please note that the current posi tion can also arise after another move order: 4.0-0 lll gf6 5 .d4. After 5 .0-0 it is risky to take the pawn with 5 . . . lll e 4; although it won ' t lose by force, White has a very strong initiative after 6 .• e2 lll f6 7 .dc5 e6 8 . l:td 1 . The ensu ing positions have not been deeply analysed yet, but this might change in the future if B lack stops being afraid to take on e4. Therefore 5 . . . cd4 6 .• d4 a6 7 .$.. d 7 �d7 .

White can play 8.c4 g6 9.lll c 3, as in Tiviakov-Ivanchuk, Montreal 2007, where White managed to create serious problems for Black. The pawn structure is like in the Maroczy system, but White does not have a bad light-squared bishop. Ivanchuk himself played differently and won a nice game against Garry Kasparov in Linares 1 99 1 with 8.�g5 h6 (better is 8 . . .e6, as in the encounter Rublevsky-Bologan, Poikovsky 2003 . Eventually Black should equalize, but his task is far from easy ! ) 9.�f6 gf6 I O.c4 e6 1 1 .lllc 3. Variation C Playing 4.0-0 White can opt for different positions than those arising after the moves 4.c3 and

38

4.d4. In addition, White i s able to keep his l ight-squared bishop by moving it to fl or c2. Now B lack has two main answers : 4 . . . a6 and 4 . . . lll f6.

After 4 . . . a6 it's White's turn to choose. After the normal 5 .�d7 �d7 6.d4 cd4 7 .°ifd4, followed by c2-c4, the game takes on a character very similar to the one studied in Variation B). After 7 . . . e5 8 .• d3 h6 9.c4 b5 White can play I O.lll a 3 , I O.lll c 3 (as seen before) or even I O. lll fd2, as in the game B ologan-Topalov, Eilat 20 1 2 . A completely different approach is the move 5 .�d3, which is now the most promising for White . If B lack develops normally with 6 . . . g6, White gets better chances to take over the centre with 7 . �c2 �g7 8 .d4 •c7 9 . a4, as i n Bucharest Caruana-Topalov, 20 1 2 . The latest plan by Svidler, 5 . . . lll e 5 , looks dubious, since af ter 6.lll e 5 de5 7 . a4 lll f6 B l ack has a damaged pawn structure. From my own experience I know that this can be very dangerous for B lack. In the game Carlsen Svidler, S tavanger 20 1 3 , White failed to pose B lack serious problems. But White can clearly i mprove on his play, e.g. with 8 .lll c 3 or 8 . a5 . I believe B lack ' s best reply is 5 . . . lll gf6 6 . c 3 b5 7 .�c2 �b7 8 .• e2 e5 , similar to

the lines studied in Variation A), with excellent chances for equality or even more. After 4 . . . lll f6 5 .d4 (note that White cannot play for a draw with 5 .e5 , as in Rozentalis Tiv iakov, Vrachati 20 1 1 , since after 5 . . . de5 6.lll e 5 a6 Black is slightly better i n all lines) we transpose to Variation B ) . So the only independent move is 5 . l:te 1 , vacating square f l fo r the retreat ing bishop.

I n the game S hirov-Kasparov, Linares 1 994, a complex posi tion with chances for both sides arose after 5 . . . a6 6.�fl b6 7 . d4 cd4 8 .lll d4 �b7 9.f3 e6 I O.a4. Shirov recommends 7 .c4, with slightly better chances for White. Conclusion As we have seen, the variation with 3 .�b5 lll d 7 is very popular nowadays, with lots of games played in tournaments at all lev els ! More importantly, most of the players ( Anand, Carlsen, Topalov, Bologan, as well as the present author) encounter it with both colours . Good knowledge of this variation is essential for any S icilian player. 3 . . . lll d 7 is an excellent weapon for Black to play for a win after 3 . �b5 . With out any doubt, we will continue to see it everywhere in the future.

Especially memorable was win ning the Kavala Open, the stron gest open in Greece, and also the Bora Kostic Memorial, a strong closed tournament in Vrsac, Ser- . bia. In both of these tournaments it was highly important to achieve wins in the last or penul timate rounds - with black. In both I had the chance to use one of my new ideas at the time in the Rossolimo: I .e4 c5 2.tt:lf3 tt:lc6 3 .�b5 d6 4.0-0 �d7 5 .l:l e l tt:lf6 6.c3 a6 7.�a4 c4 8 .�c2 tt:lg4 ! ?, which in the New In Chess Key System is classified under the Moscow Variation (2 . . . d6 3 .�b5 tt:lc6).

A fe w months later I had another game with 8 . . . tt:lg4 against Cana Kevin grandmaster dian Spraggett. This one actually went even better. The idea be hind 8 . . . tt:lg4 is to get in . . . tt:lce5 and control the weak d3-square. After b3/b5 , bc4/bc4 we usually get a position with a weak pawn on c4, but if Black manages to hold on to this pawn he creates a lot of pressure, as the pawns on c3/d2 and the bishop on c I are a sorry sight in the white camp . So White goes b2-b3 , bc4 and then tt:la3 , �e2, l:tb I , and Black holds on to the pawn with l l . . . tt:lce5 and I 2 . . . l:tc8 . After all this White has a choice:

A Good Choice

Chess-wise, 2008 was a great year for me. There was some tur bulence, as I won three tourna ments and then played the worst tournament of my life (the Olympiad), but still it was a year to remember ! Old Recipes

It was also a year of creativity in which I used some well-prepared lines and novelties, like l l . . . �b6 in the Ragozin (Akopian Halkias, Plovdiv 2008) and also bringing back to life the Arbakov Gambit in the Vienna ( l .d4 tt:lf6 2.c4 e6 3 .tt:lf3 d5 4.tt:lc3 dc4 5 .e4 �b4 6.�c4 ! ) against Perunovic. I don't claim to be the only guy that has played this, but I had some nice games there.

Right now I have a database with computer games and I see that the move was played back in 2005 by the computers Pharaon 3.2 and Glaurung 0.2.3. Believe me, I didn't have a clue and I really don't think people base much of their preparation on what com puters play between themselves. During the game against Svetushkin the move 8 . . . tt:lg4 looked like a good choice if you wanted to try and complicate the game. The idea worked out well. In the complicated position that ensued after 9.'it'e2 tt:lce5 ! 1 0.tt:le5 tt:le5 I l .f4 tt:lg4 my op ponent came under constant pressure. In time-trouble he blundered and I got a really valuable point.

A) Spraggett, and in his foot steps Macieja, chose I 3.tt:ld4, which should be answered by 1 3 . . . g5 ! . In the former game I managed to show that the dy namics on the kingside lead to a good game for Black. B) But 1 3 .tt:le5 tt:le5 1 4.f4 ! ac tually relieves the pressure on White's position because the 47

c4-pawn is about to fall ! As an answer Black has multiple tacti cal operations, but as we will see in this article, if White makes all the proper moves, nothing works for Black. The best he can do is go ... tt:Jd3 and get the white bishop, when he will have some compen sation for the pawn with the bishop pair. That is a position that can be played, but you don't pre pare to get something like this ! New Recipes 201 2

All in all, I had in my mind that 8 . . tt:Jg4 was an interesting line. .

But whenever I tried to make my move l 1 ... tt:Jce5 work in analysis I banged my head against a wall ( I 3.tt:Je5 and 1 4.f4 ! ). lvanchuk tried my idea later that year, which made me very proud. But after 1 1 .tt:Ja3 he went l l . . . tt:Jge5 , which was actually not good enough. The last time I tried 8 . . . tt:Jg4 was against Pikula in 2009. This time I got some problems in the opening. Now that I knew more or less that there were specific problems in the line I decided to let it go for a while. I was happily surprised to see my friend Giannis Papadopoulos

trying the line once more last year in the Greek League against Macieja - and with a successful outcome ! Still the problem of the line remains, as Macieja played 1 3 .tt:Jd4 as well and not the criti cal 1 3 .tt:Je5 ! tt:Je5 1 4.f4 . Antonis friend, Another Pavlidis, the reigning Greek Champion, helped me with this article and he tried to save the line. As you will see in the notes to Macieja-Papadopoulos, the move 1 2 . . . 'ii'c 7 leads to a posi tion with the bishop pair and some compensation ( 1 6 . . . g6), and we believe that B lack can survive in this line. But let's face it: we are a pawn down. Conclusion 8 . . tt:Jg4 isn ' t an easy line to use. .

There aren't enough games yet (only eight so far), so I cannot provide you with any definite theory and definite conclusions. What I can tell you for sure is that there are plenty of ideas, plenty of beautiful diagram positions and lots of space for innovation. After my Kavala game against Svetushkin there was another black game with the same oppo nent, in the Serbian League later

I made some small notes on all of the computer games I found with the line 8 ... lt:lg4.

Chess in the modem information age develops with leaps and bounds. The amount of theory to be studied grows each day, and this is not to everyone ' s taste. In 1 994, for example, the Huge Da tabase consi sted of only 300,000 games, whereas now an average database has 6,000,000 games. Nowadays we see more and more players (including the world top) selecting an approach that moves away from the main theoretical lines. The players are not trying to compete in the depth of their home preparation, but choose less deeply analysed lines that do not promise a large advantage. Instead, they try to outplay their opponent in the later stages of the game .

The Latest Trends One of the variations that require a lot of theoretical work is the Najdorf Sicilian. In the Year books we have been studying different ways of avoiding it (look at earlier Surveys written by yours truly, for example ! ) . 3 .�b5 remains a popular move to avoid the Najdorf or other ex tensively analysed variations of the Sicilian Defence. At the moment we see this move being played by C arlsen, Anand (who himself became a victim of it several times), Caruana and other strong players. And we feel that a Survey has become neces sary to i nform the Yearbook reader about the latest trends and developments in the variation beginning with 1 .e4 c5 2.tll f3 d6 3.�b5 �d7 4 ..Q.d7 'i!Yd7 5.c4 (another plan, with castling, c2-c3 and d2-d4, will not be studied in this Survey) 5 tll f6 (the pawn grab 5 . . .

Vlswanathan Anand

Ottawa Tiviakov-Gerzhoy, 2007) 6.tll c3 g6 7 .d4 cd4 8.tll d4 �g7 (see the diagram above). Key Differences What we now see on the board is the pawn structure that is typical for the Maroczy System against the Accelerated Dragon. The key difference compared with the Maroczy is the fact that the light-squared bi shops have been exchanged. Although i n the Maroczy, White ' s light-squared bi shop is always bad, its ex change still favours Black, who gets more space to manoeuvre his pieces . But the most impor tant thing is that after the bishop swap it is much easier for Black to organize the freeing move . . . d6-d5 . In most cases, if Black fails to free himself by playing . . . b7-b5 or . . . d6-d5 at some 37

point, he will end up worse. White can easily stop the possi ble advance . . . a7-a6 and . . . b7-b5 by playing a2-a4, but it is not so easy to stop the plan with . . . e7-e6 and . . . d6-d5 . So most of the play we will see in this line will be about this break-through advance ! The following games clearly demonstrate the dangers in Black's position and what can happen to him if he fails (or does not want) to play . . . d6-d5 : Tiviakov-Idani, Tiviakov-Ivan chuk, Tiviakov-Collas, Bruzon Jones. And of course, this selec tion can go on, on and on . . . In the diagrammed position, White has a choice of four main plans: A) 9.0-0, B ) 9.h3, C) 9.f3 and D) 9.tt:lde2.

lead to complications after 1 0 . . . 'if e6 I I . tt:ld5 'if e4 1 2. tt:lc 7 Wd7 1 3 .tt:la8 "i!t'c4. Two pawns for the exchange turned out to be more than enough for B lack in Naiditsch-Anand, B aden-Baden 20 1 3 . Although I believe that White can i mprove on his play, it's difficult to believe that he can get an advantage here . If Black i s afraid t o g o into com plications, he can also opt for 1 0 . . . 0-0, transposing to a line which we will study later 9.tt:lde2 (Variation D). After 9 ... tt:lc6 the best move for White i s 1 0.tt:lc2. The ensuing position was quite popular a long time ago, but now it i s rarely seen. But it i s worth returning to it, trying to discover new resources for White !

Variation A 9.0-0 is a natural enough move.

Variation B The idea behind 9 .h3 is to try and finish the development with �c l -e3 and 0-0. If White suc ceeds, he will stand slightly better compared to the set-up with f2-f3, �e3 , 0-0. Unfortu nately for White, after 9.h3 the pawn on e4 remains insuffi ciently protected, allowing Black to use a tactic to solve his problems. After the correct 9 . . . f/Jc7 White has a choice be tween 1 0.b3 and 1 0.flte2.

However, here it seems less dan gerous for Black because after 9 . . . 0-0 White has no time to play 1 0.f3 or 1 0.h3, since after both moves Black equalizes easily with 10 . . Jk8 l l .b3 d5 ! !. In or der to keep fighting for an advan tage, White probably has to play I O.b3 tt:lc6 l l .�b2, although it seems that B lack is OK then after l l . . .e6, preparing . . . d6-d5 (see Krayz-Roiz, Israel tt 2004). Another possibility for Black i s 9 . . . tt:lc6, forcing White t o move his knight away from the central square d4. Now 1 0.tt:lde2? ! can 38

I O.b3 forces the game into an equal ending: 1 0 . . . °i!f a5 l l .�d2 t2Je4 ( 1 1 . . . tt:lc6 deserves atten tion as well) l 2.tt:le4 °i!fe5

1 3 .°i!t'b l f5 1 4.�c3 �e4 1 5 .'\We4 fe4 1 6.tt:lb5 �c3 1 7 .tt:lc3 . This variation i s presented in the game Bologan-Naiditsch, Spain tt 20 1 1 . The only way for White to avoid an equal ending i s to play 1 0.°iVe2, as yours truly did i n his game against Hou Yifan in Hoogeveen 20 1 2 . Although the position remains equal , thanks to the fact that all pieces are present on the board, White has more chances to outplay a weaker op ponent (or lose to a stronger one). In the above-mentioned game I managed to exploit the then Women ' s World Cham pion ' s mistake in the complica tions and win the game . Va riation C The move 9.f3 and the following set-up have always been White ' s m a i n weapon. After 9.f3 0-0 (please note that 9 . . . "i!f c7, played in analogy with Variation B, is a mistake. Anand played it once against C arlsen and lost badly. I think that Anand had simply confused two lines: 9.f3 with 9.h3) IO . .te3 tt:lc6 (other moves are worse, for example 1 0 .. Jk8 turns out to be a loss of time, since Black i s unable to carry through the . . . d6-d5 break at an opportune moment, see Tivia kov-Usmanov, St Petersburg 2004) 1 1 .0-0 a6 1 2 .a4 e6, one of the main positions for the evalua tion of the system with 3 .�b5 as a whole arises.

Survey SI 1 . 9

White has several different ways to try to stop the break . . . d6-d5 . 1 3 .tt:Jde2 occurred in the game Tiviakov-Nakamura, Hooge veen 20 1 2 . Thi s game has been analyzed deeply by the present author, and includes i n the notes all the games played after it. Al though White manages to stop . . . d6-d5 , Black gets very good and active play for his pieces, which secures equality. 1 3 .nc l is an old move, played for the first time by Sadvakasov against Kasparov in Astana I 2 years ago.

It doesn ' t prevent . . . d6-d5 . Adams repeated this move i n December 2 0 I 2 against Domin guez Perez in London, but also failed to get an advantage. Va riation D In my opinion, 9. tt:Jde2 is the most promising move for White at the moment.

9 . . . tt:Jc6 I O.f3 ( 1 0.0-0 is worse and leads us to the vari ation 9 .0-0 tt:Jc6 I O.tt:Jde2, studied ear l ier) 1 0 . . . 0-0 I 1 .0-0 a6 I 2.a4 e6 1 3 .�g5 .

We can see that in comparison to all the variations studied previ ously, White has developed his bishop to a much more active place, once and for all preventing Black's main strategic idea of . . . d6-d5 . B lack has lots of different ways to regroup his pieces and create activity. In the Main Game of

the present Survey, Caruana Anand, Sao Paulo/ B i lbao 20 1 2, presented at the end of this Sur vey, B l ack failed to put h i s pieces on the optimal places, mi ssed an obvious tactic and l ater found himself on the verge of losing. Clearly, Black must have enough resources to equal ize, but the complexity of the position prevents us from com ing to a definite conclusion on how to do so. The Final Conclusion The bishop check 3 . �b5 is be coming more and more popular. Although it doesn ' t promise much of an advantage if Black plays correctly, it remains a good idea to avoid lots of theory i n the main lines of the Sicilian De fence. Another plus for White i s that in the ensuing positions he does not run so much risk to lose (as in the N ajdorf), since after the central exchanges (when Black has played . . . d6-d5 ) White can not lose i f he doesn ' t want to play for a win. At the moment, the most promising variation for White remains the one with tt:Jde2 and �g5 . My prediction is that we will see many more games with this line in the near future . And who knows, maybe another Survey will be required soon !

has become, it can be said, a vari ation of the 2 1 st century. It i s worth mentioning that, accord ing to the database, more than half of the games have been played by titled players . Virtues The virtues of the queen ' s posi tion on e3 are considerable. The queen defends the e4-pawn and supports the e4-e5 advance . The development of the rook on d 1 will signify opposition on the central file with the enemy queen. Finally, if necessary the dark-squared bishop obtains the d2-square . The drawback to the queen ' s position on e3 is that it is subject to attack by ... tll f6-g4, against which (and also against . . . £c8-g4) the prophylactic h2-h3 is effective. In the initial position of the varia tion B lack has three main op tions: 6 . . . e6, 6 . . . �g4 and 6 . . . g6. Hedgehog 6 . . . e6 leads to a typical ' hedge hog ' with the rather unusual po sition of the queen on e3. It is amusing that the game Karpov Gheorghiu (Leningrad 1 977), and also a number of others, via the move order 1 .c4 c5 2 . tll f3 tll f6 3 . tll c 3 e6 4.g3 b6 5 . ill. g 2 �b7 6.0-0 �e7 7 .d4 cd4 8 .

evaluation for the Hedgehog : Black is slightly cramped, but he is ready to free himself at the appropriate moment. Controling the Centre 6 . . . �g4 involves the idea of ex changing bishop for knight, to strengthen B lack' s control of the centre.

The development of the bishop on the long diagonal allows B l ack to fight successfully for the key d4-point. For example, Alexeev Idani; Bitoon-Wen Yang.

Since the early eighties, when I studied Fischer's My 60 Memo rable Games, I h ave been at tracted by the move 6.�c4 against the most popular lines i n the open Sicilian. Thirty years later I still rely on thi s recipe to smash Naj dorf- and Schevenin gen-type set-ups. Usually a messy position ari ses. White castles either kingside or queen side, sacrifices a piece on e6, d5 or f5 , or starts a pawn-roller on the kingside . There ' s always room for inventiveness ! I had a lot of fun and made a high score w ith my beloved 6.�c4. But there was a slight annoy ance : when Black played 6 . �b6( ! ) in the classical varia..

up some ideas, but my opponent, tion, I was unable to reach a posi the strong GM Alexander tion to my liking. I never got anything out of the opening ex Zubarev, had to improvise as well ! I managed to score an imcept a normal-type Scheve ningen with mutual chances . . pressive victory and led the tour nament with two rounds to go. Finally, in a desperate attempt I Then I lost with black, but in the forced myself to analyse the con last round I faced the young sequences of the gambit 7 .�e3 ! ? Russian grandmaster Egor �b2 8 . tt:ldb5 , and after 8 . . . �b4 Krivoborodov with the white 9.-.We2 ! ?. This appears unsound at fi rst pieces and . . . again the gambit line came on the board ! sight, but the line surprised me It was obvious that my opponent by its richness of ideas, which I had prepared the variation dur realized after I had done some i ng the night. Okay, I ' d been on work on it. the night shift too: repeated my This continuation, speeding up old analyses, committed the pat development without wasting terns and motifs to my memory, any thought on pawns, was in and screened the critical l ines. vented by Vladimir Lepeshkin and was first played by Igor After 9 . . . tt:le4 1 0. �f7 he shook me by l 0 . . . @d8 ! ? without hesi Zaitsev i n 1 996. It is by far more tation, and he kept moving very aggressive than the previously fast. How could I be so silly to re played 9.�d3/�d5 , slow moves peat this risky variation? I started that score very poorly in the cursing myself. . . databases. Convi nci ng Practica l Resu lts With fresh impressions I went on to play the gambit and won against German WGM Melanie Ohme in good style. Nearly two years passed until I got the chance to play it again at the Staufer Open in January this year. I was amused when I dis covered in the database that no one had played the variation dur ing 20 1 2-20 1 3 , except me ! Is it really this bad? No, it i sn ' t ! I only vaguely remembered the lines I had analysed and mi xed

I t took m e some time t o pull my self together and to avoid the traps he h ad laid. After a very tense struggle I won the game 55

and earned some prize money. His novelty (later I found a game with I O . . . 'lt>d8, which was not in cluded in the databases I use ! ) forced m e to find some only moves, but theoretically Black can only hope for equality. The Critical Test of the Line More critical in any case is IO . . @f7 I l . .l:i.b l �a5 1 2 .�c4 e6 1 3 .�e4. .

an easier way to handle the prob lem: 9 . . . 'ifa5 is the move that is most often played. Understand ably, B lack wishes to reach the home port for his buccaneer queen, but thi s allows White to complete his development and establish an attacking position. As a rule, White rushes the knight to d5 , a menacing penetrator that Black cannot al low there, and after the swap on d5 White takes with the pawn, e4xd5 , and gets pressure down the e-file. In chess moves : I O.�d2 �d8 I i .ttJd5 ttJd5 1 2 .ed5 ttJe5 .

• In my opinion this i s the only real test for the viability of the whole variation. In all the other l ines White has good chances to achieve not necessarily an ad vantage, but an enduring initia tive and easier play. Only a handful of games were played with this critical continuation; not enough to assess the ensuing position. Computers like Black here . White i s forced to give a piece, or two pieces for a rook, but to play over-the-board with uncoordinated pieces and a wan dering king is not everybody 's cup of tea. Instead of the main move I 3 . . . d5 I would like to draw attention to the restrained 1 3 . . . 'it>g8 ! , a pro phylactic move that hasn ' t been played so far. No Comfortable Line for Black Most players don ' t like this kind of hullabaloo, and will look for

56

•

Here White can force the play with 1 3 .f4 �g4 ! l 4.ttJd6 ! , but with a series of accurate moves Black should hold the balance. l 3 .�b3 leaves more potential on the board at the cost of a tempo. Instead of the usual l 3 . . . a6 with . . . b7-b5 to follow (Kotronias), Black has the interesting 1 3 . . . g5 ! ?, which was introduced by Milos Pavlovic. Conclusion At the end of the nineties, Year book Supervisor Rene Olthof wrote a Survey about this gambit line, partly based on a theoretical Vladimir publication by Lepeshkin in the Russian monthly 64 98/5 . Almost 1 4 years have passed, and since then

Vladlmlr Lepeshkin

the computers have changed a lot in the chess world, especially in highly tactical opening varia tions. In my op1mon, the ' Lepeshkin Gambit' has proved its strength and withstood all attempts at refutation. One such try was Zarnicki ' s 9 . . . �g4 ! ? I O.f3 ttJe4 ! ?, but Olthof' s rec ommendation in Yearbook 5 1 , I I .�d4 ! , proved very successful in the game Polzin-Popovic in 200 I . This line i s not recom mended for Black.

If you want comfort you ' ll get inconvenience ! The strength of the gambit l ine lies in the fact that B lack is obliged to take risks and should be well prepared; otherwise he ' l l have a very hard time. ·

Rauzer Variation

SI 27. 1 (860)

An Affro nt to t h e Ra u zer by Jeroen Bosch (special contribution by Sergey Shipov)

Commenting upon a Classical Sicilian game against Rauzer (Leningrad 1 933) in his Half A Century of Chess, Mikhail Botvinnik writes that instead of 6.£e2 - when the patriarch re plied 6 . . . g6 - Rauzer later ' intro duced the move 6. ilg5 preventing the Dragon Varia tion ' [my italics ] . Indeed, Rauzer's 6.�g5 was certainly in tended to prevent the Dragon, and the move 6 . . . g6 may be con sidered the biggest personal af front to his memory.

Genesis But it was yet another Soviet powerhouse, Igor Bondarevsky, who introduced precisely this move into modem practice. In the game Gromek-Bondarevsky, Lodz 1 955, there followed 7 .�f6

ef6 8 .�e2 9.. g 7 9 .tt.:ldb5 0-0 1 0.�d6 f5 1 1 .0-0 fe4 1 2 .�d8 .!:!.d8 l 3 . tt.:le4 Jli.b2, and Black was already slightly better and went on to win. His Polish opponent Jozef Gromek was so impressed that he took up B lack' s cause in subsequent years . In the 1 960s, Oleg Chemikov started playing the Dragon ver sus the Rauzer, making the big gest contribution to the theory of this line. It would be most fitti ng to call this the line the Chemikov Variation, especially after the Russian grandmaster published his findings in SOS-3 (New In Chess, 2005 ) . In more recent times the line has occasionally been played on the highest level. Carlsen, Nisipeanu, Naer and Vitiugov are among the inciden tal practitioners. The 20 1 3 Tata Steel Chess Tour nament saw a spectacular game between Nils Grandelius and 20 1 2 j unior World Champion Alexander Ipatov. This is a good starting point for a Survey on the main line starting with 8 . Jli.c4. A Road map Following 6 ... g6, White has but l ittle choice and should take up the gauntlet if he wants to achieve an opening edge. In deed, the sharp 7 .tt.:lc6 bc6 8 .e5 de5 falls short by a wide margin (both 9 .�f3 and 9 . �d8 promise nothing), while the tame 7 . �e2 �g7 (or 7 . tt.:lb3 �g7 8.�e2) will

lead to a quiet line once favoured by Karpov versus the Dragon . This last line is playable of course, but not critical. After 7 . Jli.f6 ef6 White has done some serious damage to his op ponent's structure and more of ten than not Black will lose the backward pawn on d6. In return B lack has secured the bishop pair, and in particular the dark-squared bi shop can develop into a monster after a subsequent . . . f6-f5 . The main move now is 8.Jli.c4, and for the alternatives the interested reader is still best referred to Chemikov 's article in SOS-3. Black, of course, continues with 8 . . . �g7 .

Now, again White must follow the sharp and precipitous road with 9 .tt.:ldb5 , immediately tar geting the weak d6-pawn. For the only sensible alternative 9.0-0, see the great game Berg-Naer, German Bundesliga 20 1 1 / 1 2, which demonstrates the potential of B lack's bishop 63

1 1 .0-0-0 (for 1 1 .0-0, see Robson-Perelshteyn, St Loui s 20 1 1 ), and it i s only here that our roads diverge.

pair in this line. After 9. tt:ldb5 Black is forced to sacrifice his d-pawn with 9 . . .0-0 and White usually grabs it with 1 0.'ti!Vd6 ( 1 0.0-0 would transpose to 9.0-0; see the notes to Berg Naer) . Now there is no need to consider any other move than 1 0 . . . f5 , opening up the position for Black's ' Dragon ' bishop, and starting counterplay in the cen tre.

an important i mprovement for Black, i nstead of Ipatov 's recap ture 1 6 . . . fe6). Both 1 2 .tt:ld5 and 1 2 .f3 have been tried in practice, but neither move is convincing. Shipov himself notes the odd sil icon move 1 2 .l:thf l , but has diffi culties believing i n the idea - is this really the way forward for White? Conclusion In conclusion, Black's offensive 6 . . . g6 seems fully playable at present, which is mainly due to the fairly new move I I . . . �b6 in the main line. Unless White really wants to go for 1 2 .l:thf l , he should perhaps seek other ways to combat the Chemikov Variation.

There are many Sicilian varia tions that are considered ' smelly' to say the least, and they tend, slowly but inevitably, to remain only as dust on an old book left unopened for many years . This might have been the fate of the 6 .2.d7 Rauzer Variation, partly because of 1 O.e5 , followed by Kupreichik ' s 1 3 .tt::l b 5, which was thought to be crushing.

was not the researcher. Two grandmasters have kept playing it as Black: Konstantin Shanava and Daniil Dubov. One might make an obj ection about the youth of the latter, but Dubov re cently drew against some of Rus sia's best players, although he did not play this exact line. We decided to scrutinize his games in order to understand where the old anal ysis went wrong, or where Dubov did. And to our satisfaction we discovered that Black was not losing at all and that White, in fact, had to work hard to get an advantage ! Two Known Paths Still, the results are really poor for Black, since the position after l 3 .tt::l b 5 is known to be rather tough to play without a computer as the defender. But does tough mean unsafe? We shall see. 1 O ... deS 1 1 .feS e6 1 2.0-0-0 ..Q.c6

New Life But sometimes there is a pioneer whose sigh breathes new life i nto an almost-forgotten line. Vladi mir Kramnik is one of them, and he is getting more and more fol lowers. But in the present case he

There are two known paths to be analysed here : l 3 .tt::l b 5 and

Danlil Dubov

l 3 .�b5, although a 1 99 1 recipe from Polgar with I 3.�c4 might also be a contender. After 13.tt::l bS Dubov got per fectly reasonable positions until move 25, but he lost the two games which we have chosen as the main ones for this Survey due to the i nherent difficulty of the task he had set himself. 13.�bS leads to a difficult choice for B lack: I 3 . . . tt::l d 5 seems to us the most sensible op tion here, leading to endgames that are not easy to assess (see Vallejo Pons-Shanava) . 13.�c4 is an almost unexplored track. We did manage to hold the position to a draw as Black, al though some crushing lines can be found here. Currently there i s not enough material available on this line to draw any definite conclusions. 69

Conclusion So far, no refutation of this line has been found, but if White

wants to have an easy, risk-free way to continue, he should go for the Vallejo ending, in which, in

most cases, the stronger player may be able to demonstrate his better technique.

All the more reason to admire the dedication to thi s system of the few true fans that are left. One is reminded of Croatian GM Zdenko Kozul, who doesn ' t play anything else in reply to l .e4. But this time I was inspired to write a Survey on the games and ideas of another Croatian grand master: Alojzije Jankovic. He treats the diagram position rather unconventionally. After 1 2. � e2 he immediately castles 1 2 . . . 0-0 with meets 1 3 .e5 and 1 3 . . . tll h 7 ! ?. Alojzije Jankovic

The Rauzer Variation in general , and this position in particular, have been the cause of serious headaches for Black in recent times. His play in the opening looks natural, but the results are often unsatisfactory. I ' ve lost so many games in the Rauzer that maybe it would be more sensible to quit this dangerous system al together and find something more reliable. What stops me from taking this cowardly deci sion is a clear understanding that whatever opening line I chose, the final result would be deter mined by the rest of my play anyway. 62

bishop. An important defensive resource is the push . . . f7-f6 (f5 ) at the right time. This simple strategic concept is universal for such positions, so I have tried to explore it in differ ent variations. White has tried 1 4. tll e 4, 1 4.a3, 1 4.h4 and 1 4 . � g3, but could not get a real edge. The knight' s position looks awk ward, but it definitely makes sense. An additional piece near his king allows B lack to meet White's offensive with more op timism. Jankovic's further plan involves . . . a6-a5 , usually with the eventual . . . � c8-a6 . If he doesn ' t get mated, his powerful pawn centre and counterplay along the half-open b-file give him real chances to seize the ini tiative . White's offensive loses power without the light-squared

An I m portant N u a nce

White can insert 1 2 .a3 ! � a5 ! tll d 7 ! 1 3 . � e2 0-0 1 4 .e5 (Durarbeyli-Jankovic, Rome 20 1 1 ), which brings into play some additional i mportant nu ances and also requires careful study.

Survey SI 29. 2 A less principled way for White

is the exchange of pawns on d5 on move 1 3 : 1 2 .a3 � a5 1 3 .ed5 cd5 (Hovhannisyan-Robson, Chennai 20 1 1 ) or move 1 4 : 1 2.a3 �a5 1 3 . � e2 0-0 1 4.ed5 cd5 ( 1 4 . . . ed5 ! ?) (Negi-Krush, Wijk aan Zee 2008 ; Zhao-Kritz, Pawtucket 2008).

The Di rect Attack

White has tried different contin" uations, but all his plans are con nected with a direct attack on the king. 1 2.�e2 0-0 1 3.e5 tl:lh7

and now the lines fork:

Kravtsiv-Jankovic (Game 2 ) . More promising for White looks 1 6.g4 ! ?, but as shown in the comments to the game, Black can hold.

C) 1 4.h4 �a5! I found three games with this position - too l ittle practical material for a final conclusion. 14 . . . � a5 is the safest move, of course. I analysed the original Jankovic-like concept 1 4 . . . a5 in its pure form, but it turned out to be too dangerous.

Conclusion

Jankovic 's opening concept is original and principled. B lack concentrates his forces around his king to beat off the direct en emy attack. The knight on h7 symbolizes the ideal of genuine loyalty to the overlord. If B lack manages to exchange his light squared bishop via a6, his diffi culties are usually over. Frankly speaking, thi s way to fight for the win is not suitable for everyone. However, the analyses show that B lack 's position has significant defensive potential and serious counterattacking resources. The lines with the knight on d7 are less safe for Black - insofar as one can talk about safety in relation to this system.

position after 1 9.�f4xh6

What is more important for Black? Simplifying the position ( 1 4 . . . f5 1 5 .ef6 tl:if6), bringing an additional piece to the kingside ( 1 4 . . . �e7) or ignoring White's ac tivity with 1 4 . . . a5 and 1 5 . . . Aa6?

How would you evaluate this end game? Should Black immediately break through in the centre or fix White's pawns on the dark squares first with . . . h5 and .. .f5 or . . . g6?

What would you play as Black: I 9 . . . gh6, I 9 . . . .Q.e5 or 1 9 . . . tl:ieS ?

After 8 .tll f5, 8 . . . g6 has always been the most popular move, with hair-raising tactical compli cations after 9.g5 . Various Year book Surveys can be found on this line; the last time I wrote about it was in Yearbook 99. An-

other possibility is 8 . . . tll c 6 - see Yearbooks 93 and 94. A third possibility is 8 . . . h5, which has been played quite often lately. The database gives Koch-Andruet, Marseille 1 989, as the oldest game, but almost all other examples are from the new century, which is still quite young . It's interesting to find Maxime Vachier-Lagrave, Da vid Navara and Hou Yifan among the black players . We get quiet positions in which White is at best slightly better. Gilles Andruet the originator of 8 hS

Main Line The main line is 9 .g5 tll e4 1 0.tll g 7 �g7 1 1 .tll e4 d5 I 2 .tll g 3 d4 I 3 . �d2, and now either 1 3 . . . �dS or I 3 . . . tll c 6. In both cases White remains a fraction better thanks to his influence on squares e4 and f5 , but as the examples in the Game Section show, Black is not without coun terplay, thanks to his pawn on d4.

Conclusion With 8 . . . h5 (and, incidentally, also with 8 . . . tll c 6) B lack in any case avoids the enormous tacti cal complications following the main line of the Perenyi Attack (8 . . . g6), but the positions that arise on the board are easier to play for White.

M This Survey presents a particular path against Black's counterplan in the English Attack. In Year book 76, Alon Greenfeld made the first steps towards analysing the system' s basis, which is why I recommend the reader to study this earlier Survey. Eight years of debate have passed and we will try to look at all the changes and at the current state of the varia tion. As I have been on the white side in two recent games, I will show the reader my conclusions. Desta bilazation

To experts of the system, the move I O.a4 is familiar, although a beginner might play differ56

From a strategic point of view this should be the main option, since Black aims to open files on the queenside and the white king doesn't seem to have a safe place to go. However, with precise play White can thwart B lack ' s intentions and aspire t o a superior endgame. A) After 1 0 . . . b4 l 1 . tll a2 B lack is at a crossroads:

White follows the indicated stra tegic route, but in my opinion the drawback of this move is that after t2J e2 and � d4 it could take long to secure the white king. t2J a4 1 8 .0-0-0 ! ( 1 8 . . . �g7 1 9 . 'i!Vg4 0-0-0 20. t2J db5 ! ab5 � a4 1 9. t2J a4 2 1 . �c S ± ) t2J 20. e6± .

White's idea is to carry out a direct attack in the centre, but he should keep in mind that the black position is more vulnera ble once the bishop is positioned on b7 , so if B lack delays this natural developing move, White should play some useful waiting moves, waiting for the best mo ment to carry out the f4-f5 break : 1 3 . . . �c7 1 4.0-0 ( 1 4.f5 t2J e5 1 5 .0-0 is unclear) 14 . . . �b7 ( 1 4 . . . �e7 1 5 .b4 cb3 1 6.cb3 = ) 1 5 .fS e 5 1 6. t2J de2 t2J c5 1 7 . t2J g 3 , initiative and White ' s is crushing. 1 4.fS tll c5 1 5.fe6 fe6 1 6.ifg2 g6

This new approach radically changes the perception of the po sition . White doesn ' t yet decide where he will put his king, and the text move hinders Black's game . The pressure along the open file forces Black to take preventive measures and after that, with a strong manoeuvre, White forces the exchange of the dark-squared bi shops, generat ing new weaknesses and keeping the centre unstable. In his Survey in Yearbook 76 (2005 ), Alon Greenfeld com-

White's advantage is obvious better king and piece coordination. However, quick action is war ranted: what would you play? (solution on page 246)

The same pawn structure as in the previous quiz. This time other measures are necessary. How would you open up the position? (solution on page 246)

The black king in the centre is White's main target. The big ques tion is: how to get to him. What would be your choice? (solution on page 246)

Recent Trends

Meanwhile, in recent years we have been looking at a double phenomenon with the renais sance of the line 6. �g5 (with interesting new ideas for both sides, like 6 . . . lll b d7) and some decline in the popularity of the English Attack, partly because of fashion and theoretical satura tion , but also because B lack has improved his defence and deeper concrete lines have appeared, for example (I ' m j ust going to list two of them in the . . . e5 scenar ios) 8.f3 h5 and 8 . f3 �e7 9 . � d2 0-0 1 0. 0-0-0 a5 . Different Piece Placement

As opposed to the Scheveningen system, where pushing the flank pawns with aggressive inten tions was played a long time ago (Paul Keres introduced his fa mous attack in the 1 940s ), the development of such schemes in the Najdorf Variation and their growing reputation are more recent. The idea 6.h3 was used by Bobby Fischer in the 1 960s . The piece placement involving �e3, f3 , g4, �d2 and 0-0-0 was intro duced in the late 1 970s by Eng lish, Hungarian and Spanish chess players . Over the years it has become the most popular way to meet the Najdorf Varia tion. 46

In that context, players on the white side in the line 6 . �e3 e5 7 . lll b 3 have devoted their atten tion to a different piece place ment in recent months, with the inclusion of the moves h2-h3 (which looks like a preventive move but it also prepares g2-g4) and � f3 , with a later 0-0-0 and g2-g4 . The position of the white queen is a main theme in White's plan. There are some differences com pared with the placement on d2 in the English Attack; some of these seem to be of interest, and they form the subject of the present Survey. * White has better control of the d5 -point, one of the most i mpor tant operational bases in this Boleslavsky/Najdorf centre.

Alexey Shirov * From f3 the queen can protect h I , which enables White to quickly play the g4-g5 break in the positions in which Black plays . . . h7-h6 in reply to the advance g2-g4. * Queenside castling immedi ately makes the J:r a l operative on the d-file. In some cases an X-ray on B lack 's queen allows a good repositioning of the lll b 3 - tradi tionally a problematic piece in this scheme - with lll c 5 ! , a well known resource in the English Attack. * The queen can more quickly be involved in offensive actions on the kingside, usually going to the g-file. * The main negative feature of the queen's manoeuvre is the loss of its defensive functions. For example, White should be wary of tactical motifs on c 3 , e.g.

Survey SI 1 4. 8 the Sicilian standard sacrifice .. Jk 3 as well as the sequence ... tll b 6-c4-a3 . * In this scheme, White 's f-pawn is temporarily blocked; for its participation in the fight White needs to move the queen again. This idea has already been employed by great masters like World Champion Vis wanathan Anand, A lexey Shirov, Gata Kamsky, Ivan Cheparinov, Pentala Harikrishna and many other top players . In the study of the concrete theory of this line I have concentrated on today's most popular line, 7 .. � e6 8.h3 £e7 9 . 'it'f3 , but there is an important alternative worth mentioning: the 8 . . . t2l bd7 idea, intending to first develop the queenside by delaying the move . . . �e7; but that could be material for a future Survey ! .

advance his queenside pawns aggressively, e.g. . . . a6-a5 or . . . b7-b5 , depending on White 's 1 0th move. * Lines with . . . a6-a5 are related to the . . . a6-a5 line against the English Attack. White could play the same ideas here : preven tive moves like a2-a4 or � b5, combined with an initiative on the kingside. * Lines with . . . b7-b5 are played after White's occupation of the d5-point, generally comple mented with play on the light squares with ..Q. d3 after the ex change on d5 , which leaves a pawn on this square . The Line 1 0.0·0·0

Move Orders and Main Ideas

Starting from our basic position, Black has several different moves. The most i mportant ones are 9 ... 0-0 (the subject of thi s Survey) a n d 9 . . . t2l bd7, along with the less popular lines, which will be dealt with in the second part of this Survey. The former idea prevails in today 's practice, albeit by j ust a slight statistical margin. After 9 ... 0-0 White has various ways to set up his pieces, starting with the moves (sometimes by transposition) I 0. 0-0-0 and 1 0.g4. B lack, too, used to play numerous alternatives at thi s point, including independent plans in repl y to both White 's critical set-ups. But before showing some standard ideas from this concrete line, let me point out the following: * Differently from the 9 ... t2l bd7 line - where the priority i s piece play; in these lines with quick castling Black intends to

Black has multiple options at this point, but two of them have emerged as the main lines . For the other options , the reader may take a look at the notes to the model games. The first option, IO ... 'ifc7, may appear in the I O.g4 line, because White exclusively plays I 1 .g4 in this order. Now the immediate I I . . . a5 is very interesting, lead ing to complex play with chances for both sides, as in the game Hedlund-Lafarga Santor roman, er 2007. However, in practice, the more common move is I I .. Jk 8 , when after 1 2 . @ b I a5 ! Black used thi s flank advance to create counterplay and fight for the initiative (see the recent game Anand- I ' Ami,

Wijk aan Zee 20 1 3). Mean while, White c an improve with 1 2 .g5, and now the knight retreat leads to a slightly better position for White (see the games Fedor chuk-Baj arani, Nakchivan 20 1 1 and Nepustil-lbragimov, er 2008) , and thi s might be a strong argument for a faster . . . a6-a5 advance. The second idea i s standard in this line and, again, i n good Si cilian tradition : IO ... b5, with the continuation I l .g4 b4 1 2 . t2l d5. Now I 2 ... £ d5 is the weaker capture (see the game Hnydiuk Figura Gajo, Police 20 1 1 ) ; 1 2 . . . tl:l d5 i s correct. After 1 3 .ed5 the option of I 3 . . . ii.. d7 is inter esting, with the idea of . . . f7-f5 , a s i n Tu Ifer-Ottesen, e r 20 1 1 , but the main line is 1 3 . . . i. c8 14 . ..Q. d3 a5 (other option is 1 4 . . . tll d 7 , a s in Drozdowski-Gajewski , Chorzow 20 1 3), when White chose the quiet but interesting 1 5 . t2l d2 in Harikrishna-Leko, Wijk aan Zee 20 1 3 , but there is also the more adventurous 1 5 . t2l c5, with complex play, as you can see in the games lbragimov-Morozov, er 2009 and Shirov- Volokitin, Eilat 20 1 2 . The Line 1 0.g4

If Black wants to play a plan with . . . b7-b5, he will be a tempo behind compared with the schemes in the preceding games. The game Palac-Burg, Eilat 20 1 2, is good proof of this, as well as other games mentioned in the notes. The I O . . . g6 idea, relatively unex plored, is interesting and is based on conceding h5 to the king 's knight. In Maze-Alina I ' Ami, Reykj avik 20 1 2, very complex play ensued after 1 1 .0-0-0 t2l bd7 � c8 1 2 . @b l 1 3 . t2l d5 � d5 1 4.ed5 e4. Other less explored ideas for B lack are given in the notes to that game. 47

The main line and the most stan dard try is 1 0 . . . a5 .

Concl usion and Addendum

The line 9 ... 0-0 leads to a lively game with chances for both sides, both after the reply 1 1 .0-0-0 and after l l . g4. A good knowledge of the main strategic and tactical themes in these lines can make a big difference in practice . Meanwhile, as the model games in this S urvey show, statistics ¥e strongly in White's favour (in my base the score is 66.4% 3 3 .6%). This may show that this line is easier for White or that, because it is brand new, Black stil l has to build up a better de fence. I would like to end this Survey by acknowledging the collabora tion of my friend David Borensztajn, who has revised and corrected my English text. In Part II of this S urvey we wil l look at 9 . . . lllb d7 - the second-most popular line - as well as other less common lines for Black, like 9 . . . lllc6 and 9 . . . h5 .
