"I almost got into a nice trap" 

Round 4 of the Grand Prix London was marked with two decisive games. In one of them Alexander Grischuk outplayed Shakhriyar MAmedyarov in a tough fight. Russian GM made a commentary on his game especially for our website.

Alexander GRISCHUK - Shakhriyar MAMEDYAROV
Grand Prix London, Round 4
Spanish Game
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.d3 d6 7.c3 0-0 8.Nbd2 Re8 9.Re1 Bf8

10.d4
We offer you Grischuk's commentary below: "I made a quite rare move. Usually 10.Nf1 is played here, I also played so against Almasi at the recent Olympiad.

10...b5 11.Bc2 exd4 12.cxd4 Bg4

Shakhriyar's answer was really stiff; he practically forced me to play h3-g4 with his last move. However, it wasn't obviously beneficial for black. 
13.h3 Bh5 14.g4 Bg6 15.a3 A half temporizing move in a tough position.
15...h5 Аnd I don't really like this move
16.g5 Nh7 17.Nf1 Qd7

18.Kg2 was suggesting itself, however, it seems that 18.Kh2 was much stronger. For instance, if black will play in the same way as in the game, the king avoids Kf4+ and after opening of g-line feels much better on h2. Perhaps, Black still has to play so, because this plan seems as most logical one. 
After 18...d5 everything is forced, so I should go on sacrificing... I can't allow black knight to move to e6 and later on c7-c5. If I won't let it doing so by playing b2-b4, I will get a6-a5 in response - and I can forget about the attack on the kingside. 
19.e5 Bxc2 20.Qxc2 g6 21.Be3 Nd8 22.Rac1 Rc8 23.Ng3 c6 24.Nh4 Ne6

25.Nxg6 fxg6 26.Qxg6+ Ng7 27.Qh6

27...Nf5? I think this was a blunder. After 27...Ве7 some kind of a tough position would be on the board. For example, in the case of 28.g6 Nf8 29.Nxh5, there's 29...Nf5. Аnd 28.Nxh5 Nxh5 29.Qxh5 would be followed by 29...Qf5. Anyway, I don't think white stands worse in this position, 28.Qg6 could be played for instance; but that would probably lead to threefold...

Аfter Shakhriyar's move black's position is hopeless, I should only move my pawns accurately.  

28.Qxh5 Nxg3 29.Kxg3 Bg7 30.Qg4 Nf8 31.f4 c5 32.Qxd7 Nxd7 33.dxc5 Nxe5 34.fxe5 Bxe5+

35.Bf4 Bxb2 36.Rxe8+ Rxe8 37.Rc2 Bxa3 38.c6 b4 39.c7 Rc8 40.Rc6 b3 41.Rxa6 Bc5 42.Ra5 Bb6 43.Rxd5 Bxc7

This is the last moment I would like to mention. I almost got into a nice trap. When I was planning to go on this position I wanted to play 44.Rb5 with an idea to win some tempo, but then itturned out that black has 44. Rb8!! And Black... wins!"


Shakhriyar Mamedyarov tried to be the author of the penultimate mistake  

44.Bxc7 Rxc7 45.Rb5 Kg7 46.Kg4 1-0
