Veselin Topalov - Gata Kamsky

Round 7
Chess Challengers 2009
Sofia

With only two games left from this spectacular match, Veselin has White pieces and one may be sure that he will do his best to determine the outcome yet in game 7, but without taking unnecessary risks. Kamsky still has his chances as well, so the end of this match turns into a real thriller. Stay tuned at 14.00 CET.

1.e4 e6 2.d4 d5 3.Nd2 Both players follow game 5 - we got accustomed to the fact that every game there is completely new opening.

3... c5 4.exd5 This time Topalov eneters the main lines of the Tarrasch variation in French Defense.

4... Qxd5 4...exd5 leading to isolated central pawn is rarely seen these days.

5.Ngf3 cxd4 6.Bc4 Qd6 7.O-O Nf6 (7... Nc6 8.Ne4 is too dangerous.)

8.Re1 A rare but venomous line.

8... Be7 ( For some time the line 8... Be7 9.Ne4 Nxe4 10.Rxe4 Nc6 11.Nxd4 e5 12.Bf4 exf4 13.Nxc6 Qxd1 14.Rxd1 bxc6 15.Rde1 Kf8 16.Rxe7 Be6 17.R1xe6 fxe6 18.Rc7 h5 was very topical but Black eventually demonstrated the correct way to play.)

9.Nb3 Nc6 10.Nbxd4 Nxd4 11.Nxd4 (11.Qxd4 Qxd4 12.Nxd4 Bd7 is similar to the ending that may happen in the main line, the difference is the inclusion of Re1 and Be7, and is about equal.)

11... O-O 12.c3 Veselin prevented his opponent from playing double-edged lines involving castling queenside, on the other hand Kamsky comfortably developed his kingside. Besides the standard 12...Rd8 Black has the interesting option 12...e5.

12... Bd7 Although this is the usual way to develop this Bishop it seems inaccurate in this moment. (12... Rd8 13.Qf3 Nd5 is a natural way to play Black position.)

13.Qf3 Qb6 14.Bb3 (14.Bf4 - the move Qb6 was meant to prevent is quite interesting but with this match standing Topalov avoids unnecessary risks. 14... Qxb2 15.Rab1 Qa3 16.Rxb7 favors White.)

14... a5 15.Be3 Bc5 16.Rad1 All White pieces are centralized now.

16... a4 17.Bc2 (17.Bc4 e5 18.Nf5 Bxf5 19.Qxf5 Bxe3 20.Rxe3 Rfc8 is fine for Black. Topalov prefers to sacrifice a pawn.)

17... Qxb2 18.Bg5 The game becomes really interesting - attack vs. defense - exactly their strong sides.

18... Nd5 (18... Bxd4 19.Rxd4 Qxc2 20.Bxf6 Bc6 21.Rg4 g6 22.Qe3 Qf5 23.Rf4 Qd5 24.Rf3 is losing.)

19.c4 ( The forced play goes on but after 19.c4 Bxd4 20.Qd3 f5 21.Qxd4 Qxc2 22.cxd5 Qxa2 White still has to prove his compensation.)

19... Bxd4 20.Qd3 f5 21.Qxd4 Qxc2 22.cxd5 Qxa2 23.Qb6 The last moves were forced for both players. In the current situation White has very centralized pieces but the 'a' pawn is dangerous and should provide sufficient counterplay.

23... a3 24.Be7 (24.Qd6 Ba4 25.Qxe6+ Rf7 26.Ra1 Qc4 27.Be7 a2 28.d6 would lead to approximately equal ending.)

24... Rfe8 ( Veselin began thinking over the position and nodding his head. Did he miss 24... Rfe8 25.Qd6 Kf7 26.Rxe6 Qb3 27.Ree1 Qa4 Clock readings: 0.44 0.40)

25.Qd6 (25.Qxb7 Ba4 26.Ra1 Qxd5 27.Qxd5 exd5 28.Bxa3 would leave White struggling to draw for many moves.)

25... Ba4 This move took 30 minutes and deprives Kamsky of any chance to fight for advantage. Just the contrary - he has to be careful in the forthcoming time trouble.

26.Qxe6+ Kh8 27.Ra1 Qc4 28.Rec1 (28.Rxa3 leads to equality. Topalov wishes to exploit opponent's time trouble but is playing with fire.)

28... Bc2 29.Qd7 a2 30.d6 b5 31.Qb7 Reb8 (31... b4 32.d7 Reb8 33.d8Q+ Rxd8 is winning for Black)

32.Qc7 Rc8 And this is a serious mistake. 32...Bd3 would let Black keep his advantage while this is outright losing the game and the match.

33.Qxc4 Rxc4 34.d7 Bb1 35.Rd1 Kg8 36.d8Q+ Rxd8 37.Bxd8 Bc2 38.Rdc1 b4 39.Rxa2 b3 40.Ra8 Kf7 Kamsky made his control move but being a Rook down it doesn't really matter.

41.Rb8 Ke6 42.Re1+ Kd5 43.Be7 Ra4 44.Bf8 Ra7 45.h4 Black resigned. Veselin took great risks this game but was rewarded for his courage and is the winner of this match. 1-0
