(1) Topalov,V (2796) - Kamsky,G (2725) [C07]
World Chess Challenge Sofia BUL (7), 26.02.2009
[Mihail]
1.e4
e6
Kamsky's opening strategy in this match can be described quite simply: play on dark squares against 1.d4 and on light squares against 1.e4. From psychologycal point of view, it is interesting that he does not shy away from repeating the opening that caused him a defeat in the 5th game.

Remarkably, it is Topalov who deviates from the previous game with white, despite the favourable result.

13.Qf3
This kind of position is difficult to evaluate on the basis of general principles. It all depends on piece activity and concrete details, since the centre is wide open and structures are mobile.
13...Qb6
This is a new move. Previously 13...Qc7 had been played. The placement of the queen on b6 and the whole plan based on a7-a5-a4 is typical for the lines with a black Isolani on d5, resulting after 4...exd5 instead of 4...Qxd5.

When sacrificing the b2-pawn for the sake of piece activity, Topalov might have been inspired by a famous game Karpov-Vaganian, Skopje 1976. Karpov, too, ignored Black's queenside plan and obtained a decisive attack on the other wing. In that game, Black had played ...exd5, though.

Despite White's strong centralisation and the weakness of the dark squares from the kingside, the situation is anything but clear. Kamsky's last move defends the e6-pawn and clears the path for the a4-pawn. Speaking about Kamsky's repertoire as a whole, we can notice certain similarity with one of the main lines of the Gruenfeld (8.Rb1, 10...Qa5+ 11.Bd2 Qxa2). White's initiative in the centre and on the queenside looks dangerous, but the a-pawn can become a fast runner.

[At this height of the game, Kamsky was getting short of time already. This explains why Topalov rejected the line 24.dxe6

, when Black would stabilise the position, with good chances to reach the 40th move without any significant damage.]
24...Rfe8
25.Qd6
25...Ba4
[I am pretty sure that, even with lots of time on the clock, many grandmasters would choose precisely this move, which, according to the engines, spoils Black's advantage. Neither 25...Kf7!?
26.Rxe6
; nor 25...Bc8!?
look too inspiring for humans, but the computer evaluates the position as close to winning for Black. I suspect that deeper analysis will reveal that humans are right at least in one of the cases, but this is beyond the scope of an express report.]

[It is hard to give a final evaluation to this move. Objectively speaking, it may be said that it leads White on the verge of defeat, but from psychologycal point of view it defines an approach that eventually won the game for White. In severe time trouble, it would be simply impossible for Kamsky to find his way through the highly irrational variations. After the safer 28.Rxa3
a draw would be the most probable result, for instance 28...Bb3
(The elegant 28...Bc6?
, relying on the weakness of the first rank, is refuted by the echo-move 29.Bf6!!
after which it appears that the eighth rank is weak, too!) 29.Rxa8

It may seem that White is one tempo ahead in the fierce pawn race...
31...Reb8?
[Kamsky moves his rook one move too early... After the correct 31...b4!
32.d7
he needs to play precisely 32...Reb8!
in order to keep the b4-pawn defended. After 33.d8Q+
Rxd8
34.Bxd8

32.Qc7!
Suddenly, Black's pieces are hanging.
32...Rc8?!
[Only this move loses the game, but with little time left on the clock and with the clear feeling that something went wrong in a favourable position, it is almost impossible to find the saving move 32...Bd3!!

A tragical game for Kamsky and, to a certain extent, a tragical match, too. We could say that he lost two games because of playing too slowly and another one because of playing too fast in the critical phase. This would be only half of the truth, though. One should also praise Topalov's excellent practical abilities, which allowed him take advantage of most of the favourable moments. Moves like 21...Rc7!! from the second game and the risks he took in the last game make him an entirely deserved winner of this hard fought match. 1-0
