Descrição: chess, psychology
After 30...b6 Black’s knight would remain forever trapped. 31.Rxc5 dxc5+ 32.Kxc5 Nxa4+ 33.Kd4 Nxb2 34.Bb5!+-
Now White is winning. The bishop has a dual role; taking away squares for the knight and supporting the unstoppable d pawn. 34...a4 35.d6 exd6 36.exd6 Rd8 37.d7 Kf6
38.Re1 The final precise move, cutting off the king and threatening Re8.
38...a3 39.Kc3 Ra8 40.Re8 Na4+ 41.Bxa4 Great technique by Vasja! 1–0
10...g5 What else against g4? 11.Nhf3 — and it transposes to 9...g5) 10.Bh2 Bh5 (10...Bxh3 11.gxh3 gxh4 12.dxc5 Bxc5 13.0-0-0 Qd7 14.Qa4²) 11.Nhf3 and White has easier play as his pawn structure is healthier. For example: 11...c4 12.Qd1 Be7 13.Be2² with the idea to trade bishops after Ne5 and then e4 comes. Lukewarm moves like 8...Be7 play into White’s hands after 9.h3 Bh5 10.g4 Bg6 11.Nxg6 hxg6 12.Bg2² and White has achieved what he set out to do; to gain the advantage of the bishop pair. 9.h3 Bh5 10.g4 Bg6 11.dxc5! A very nice decision, one which is not so typical for the ‘London’: ‘Londo n’: White opens the centre with the idea of long castling.
Total equality results after 11.Nxg6 hxg6 12.Be2 cxd4 13.exd4 (13.cxd4 Bb4 14.f3 Bd6 15.Bxd6 Qxd6=) 13...Bd6 14.Be3 Qc7 15.0-0-0 0-0-0 16.Kb1 Bf4=; It was not a good idea to hurry with 11.0-0-0? because Black has 11...c4! and White is under attack. 11...Bxc5 12.0-0-0 0-0-0 Black decides to play ‘safe’. Very risky would be 12...0-0 13.Nxg6 hxg6 14.Be2 and White’s attack is the more real on the kingside after h4-h5. 13.Bb5 White continues with very direct play which was probably not necessary. A more solid option was 13.Nxg6! hxg6 14.g5 Ne8 (14...Nh5 15.Bh2 Bd6 16.Bxd6 Qxd6 17.h4² and Black’s knight is out of play.) 15.c4 Bd6
(15...d4 16.Ne4 Bb6 17.Bg3²) 16.Bxd6 Qxd6 17.Bg2 Nc7 18.Kb1² and White’s bishop is great on g2. 13...Bd6 14.Qa4 Adding more pressure to c6 and threatening Nc4. 14...Bxf4 Forcing an endgame with 14...a6 reveals small, hidden tactical possibilities for White after 15.Bxc6 Qxc6 16.Qxc6+ bxc6 17.Nxg6 fxg6 (17...hxg6 18.Bxd6 Rxd6 19.Nc4! Rdd8 20.Ne5±) 18.Bxd6 Rxd6 19.g5 Ne8 20.f4² and his better structure guarantees a long-term advantage. 15.exf4! Again White plays the most unpleasant move, changing the structure and putting new challenges to Black. The biggest problem for Black is his bishop on o n g6 which never feels safe. Black would have a comfortable position after the alternative 15.Qxf4 Qc7=
15...Qc7 Black removes himself from the pin and takes aim at the pawn on f4. Also logical was 15...a6 but after 16.Bxc6 Qxc6 17.Qd4² White has easy play on the dark squares. 16.f3? With this prophylactic move White loses his advantage. The idea was to restrict a knight from f6 taking the e4-square under control. Very logical was 16.Bxc6! and Black is forced into 16...bxc6
(Probably White didn’t evaluate how good the position which arises after 16...Qxc6? was: 17.Qxa7 d4 but after 18.c4 Black doesn’t have real compensation for a pawn. On first sight the d4-pawn looks dangerous but it’s just apparently, not in reality. For example: 18...Ne4 doesn’t work well: 19.Nxg6 hxg6 20.Nxe4 Qxe4 21.Qc5+ Qc6 (21...Kb8 22.Qe5+ Qxe5 23.fxe5±) 22.Qxc6+ bxc6 23.Kc2±) 17.Rhe1² and White’s king is safer. 16...d4
A logical move but not the best! According to my computer the best move was 16...Na5! moving the knight from the strike, after which the bishop on b5 is totally useless and will be attacked with tempo. 17.f5 (17.Qd4 a6 18.Nxg6 hxg6 19.Ba4 b5 20.Bc2 Nc6 21.Qc5 Kb7³) 17...exf5 18.gxf5 Bh5 19.Qd4 a6 20.Ba4 b5 21.Bc2 Nc6 22.Qc5 d4³ 17.Bxc6? White continues making a mess but this time to his own detriment. The only good and safe move was 17.c4÷ to keep the c-file closed. 17...dxc3! With this intermediate move Black uses his chance to open the position in the centre and in particular against White’s king.
18.Ne4? Again too optimistic! Best was to search for chances in the slightly worse endgame which arises after 18.Bxb7+ Kxb7 19.Qb3+ Ka8 20.Qxc3 Qxc3+ 21.bxc3 Nd5 22.Nxg6 hxg6 23.Ne4³ 18...Qxc6?
Black probably made this mistake out of respect for his much higher-rated opponent. With this swapping of queens, Black’s advantage disappears. There was no reason to fear 18...cxb2+ 19.Kxb2 Rxd1 20.Rxd1 bxc6, and Black’s king visually looks weak, but White gains nothing from 21.Nd6+ Kb8 with ♣Ka8, ♣Rb8 next. 19.Qxc6+ bxc6 20.Nxc3 This unusual endgame is now approximately equal, but the better player should feel more comfortable. Both sides have weaknesses and skill is needed to play such positions. 20...Bd3 21.Rhe1 Ba6 22.Rxd8+ Kxd8?!
A very strange decision! The only justification is the desire to play ♣h5 with the idea of using a rook on h8. More natural was 22...Rxd8 23.f5 g5! 24.fxg6 hxg6= 23.Na4 Bc4 24.b3 Bd5 25.Kd2 Kc7 26.Ke2 Slowly, White improves his pieces and defends defend s his weaknesses on the kingside. 26...Kd6 27.Rd1 Nd7?!
Black just stays put, playing without a concrete plan.
