(1) Rublevsky,Sergei - Grischuk,Alexander
FIDE candidate matches Tiebreak Elista (1), 13.06.2007
[Mihail Marin]

Over the last days, most of the players started showing signs of fatigue. Some of the games ended in draws after a relatively small number of moves and some of them were not too consistent. Fortunately, the last day was a true delight from the spectator's point of view. All games were rich in strategic and tactical content and the final outcome of the match remained uncertain for a long time. Grischuk outplayed his opponent with Black in the first game and starting with a certain point never gave him a chance for survival. Rublevsky displayed superb opening preparation in the second game, where he obtained a very promissing position with Black. However, his nerves let him down at the critical moment and he went for a tempting forced line which led to simplifications and an inevitable draw. Instead, he could have squeezed his opponent in a long game, but this is history already... In the third (last) game, Rublevsky pushed a little too hard in an approximately equal position. On the 26th move he overlooked Black's simple tactical resource and went down quickly - in the game and in the match as well.

1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Bc5 5.Nxc6 Qf6 6.Qf3 bxc6 7.Qg3 h5 8.h4 Nh6 9.f3 d5 10.Nc3 Bd4 11.Bd2 Rb8 12.0-0-0 Be5 13.f4
A new step in the theoretical dispute initiated by the 4th game of the match.

13...Bd4 14.Qd3 Bg4 15.e5 Bxc3! 16.Qxc3
[We are familiar already with this kind of pseudo queen sacrifice. In case of 16.exf6 Bxb2+ 17.Kb1 Bxf6+ 18.Kc1 Bb2+ 19.Kb1 Black can force an immediate draw or play on with 19...Bxd1!? ]

16...Qe6 17.Re1 0-0 18.Be3 Rfd8
The opening is over and time has come to draw some conclusions. Each part has important strategic achievements on one of the wings, where the opponent's structure is safely blocked. From static point of view, White's perspectives are better, because Black's quenside pawns are not only immobile but also weak! However, Black is much better developed and this detail weights quite heavily in the positional balance. White needs to develop his king's bishop in such a way that it does not get exchanged, which would increase the significance of his kingside weakneses in radical way. However, this is not easy to achieve, as the further course of the game shows. These kind of complex startegic evaluations is quite typical for the Scotch Opening. The absolute truth is not easy to discover, which partly explains why it used to be such a terrible weapon in Kasparov's hands.

19.Qc5
[White needs to block the c6-pawn by physial means in order to prepare Ba6. The careless 19.Ba6? would unexpectedely lose to 19...d4! 20.Bxd4 c5!! (But not 20...Qxa2 because of 21.Bc4 Qa1+ 22.Kd2 Qxb2 23.Qxb2 Rxb2 24.Kc3 when White remains in control. The exchange sacrifice 24...Rxc2+ does not work because of 25.Kxc2 Rxd4 26.Kc3 Rxf4 27.Rhf1 and White has every chance to win this.) After 20...c5!! White loses a bishop, for instance 21.Bc4 cxd4! ]

19...a5
Just in time. The bishop will not enjoy the desired stability on a6 any more. Needless to say, White is not interested in "winning" the a-pawn because this would open lines for Black's attack.

20.Kb1 a4 21.Bd3 Bf5 22.Rc1?!
[Too optimistic. As a compensation for the exchange of the light-squared bishops, White hopes to get pressure along the c-file, but Black counterplay will prove much stronger. It would have been wiser to play 22.Be2 although Black can more or les force a draw in this case with the perpetual pursuit starting with 22...Bg4 ]

22...Bxd3 23.cxd3 Nf5 24.Bf2
From strategic point of view, this is a complete triumph for Black. However, he still needs to work out some tactical details.

24...Rb5! 25.Qxc6 Rdb8 26.Qxe6 Rxb2+ 27.Ka1 fxe6 28.Rb1 a3!
In case of general exchanges on b1, White would soon have captured the a4-pawn, creating a very dangerous queenside passer.

29.Bc5 Nxh4!
Harvest time.

30.Rxb2 axb2+ 31.Kb1 Nxg2 32.f5 Nf4 33.fxe6 Nxd3 34.Ba3 Nxe5
My first thought in this position was: "Even I would win this!" The rest of rthe moves were played by inertia.

35.Kc2 Nc4 36.Bc5 Nd2 37.a4 b1Q+ 38.Rxb1 Nxb1 39.a5 Rb5 0-1
