VIII World's Youth Stars Kirishi RUS (6), 14.05.2010
1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.e3 e6 5.Nf3 Nbd7 6.Qc2 Bd6 7.Bd3 0-0 8.0-0 dxc4 9.Bxc4 a6 10.Rd1 Qe7 For antimeran variation in recent years is more typical 10 ... b5 with a further release of a queen in c7.
11.a3
Plan with the release of a queen in the e7 of different types at one time held all-round run-in at the highest level - in a quarterfinal match between Karpov and applicants Anand in 1991. Here's how the game developed Second installment: 11.h3 b5 12.Bd3 c5 13.Ne4 c4! 14.Nxd6 Qxd6 15.Be2 Bb7 16.Bd2, Karpov-Anand, Bruxelles (m / 2) 1991. Here, according to V. Anand, black can develop an unpleasant pressure on the white kingside with 16 ... Ne4 17.Ba5 f5!? followed Rf6-g6.
By fundamentally important to assess options with the course Qe7 position leads continuation 11.e4 e5 12.h3. To her above competitors came in the fourth game of the match though a different order of moves 9 ... Qe7 10.h3 a6 11.e4 e5 12.Rd1.
11...b5 12.Bd3
Illogical. On the field d3 white elephant falls under the blows of black figures. 12.Be2 really look better after 12 ... c5 about any achievements of white talk is unlikely to account. Yet 13.dxc5 Bxc5 14.b4 (after 14.Ne4 Bb7 15.Nxc5 Qxc5 16.Qxc5 Nxc5 = Franke - Lukacs, Budapest 1988 advantage of two white elephants can not hold) on 14 ... Ba7 15.a4 has adherents among computer programs .
12 ... c5
Delay in this promotion 12 ... Bb7 13.Ng5 h6 14.Nge4 c5 15.Nxd6 Qxd6
16.dxc5 Qc6 17.e4 Nxc5 18.f3 in the party Jumabayev - Cori Tello, Puerto Madryn
2009 led to black rather inconvenient.
13.Ne4?!
The final initiative passes into the hands of blacks. After 13.dxc5 Nxc5 14.e4 e5 15.b4 Nxd3 16.Qxd3 Rd8 17.Bg5 = chances of the parties would be roughly equal.
13 ... c4!
Now the black queenside with qualitative advantage, while as a game of white in the center say no.
14.Nxd6 Qxd6 15.Be2 Bb7
Initiative on the side of blacks. Resemblance to the party Karpov-Anand, Bruxelles (m / 2) 1991 is fairly obvious.
16.Ne1
Karpov in a similar situation rather 16.Bd2.
16 ... e5
A natural attempt to emphasize the shortcomings of the last move of White.
17.dxe5 Qxe5 18.Nf3 Qc7
More precisely 18 ... Qe7!? to exclude counterplay caused by confrontation queens vertical "c".
19.Nd4
Continued 19.b3 c3 20.Rd4!? Followed by a3-a4 gave White good counterplay.
19 ... Be4 20.Qd2 Ne5?!
Obvious blunder. Queenside White had to keep under control - 20 ... Nc5!.
21.a4! Qb7 22.f3 Bd3 23.Bxd3 Nxd3 24.b3 Rfe8?
Error. We had 24 ... Rfb8, that when bargaining on the queenside similar to those that occurred in the party, Black could beat the white queen rook.
25.axb5 axb5
Obvious blunder. Queenside white must be kept under control - 20 ... Nc5!.
26.Ra5?
Ivan Bukavshin passes a great opportunity to persuade the thicket scales in their favor. After 26.Rxa8 Rxa8 in white was a remarkable 27.Nxb5!. It is clear discern implications 27 ... Nxc1 (27 ... Qxb5 28.bxc4 Qxc4 29.Qxd3 Qxd3 30.Rxd3 +) 28.bxc4 Nb3 29.Qb4 Na1 30.Qb2 was not easy, but it seems that life is a black horse standing no more than one of the two extra pawns White: 30 ... Qb6 (30 ... Qe7 31.Kf2 Re8 32.Qc3 Nc2 33.Qxc2 Qxe3 + 34.Kf1 +; 30 ... Qa6 31.Nc7 Qa4 32.Qd4 Nc2 33 . Qd8 + Rxd8 34.Rxd8 + Ne8 35.Rxe8 + Qxe8 36.Nxe8 Nxe3 37.Nd6 Kf8 38.Kf2 + -) 31.Kf2 Qa5 (31 ... Re8 32.Re1 +) 32.Na3 Qc7 33.Rxa1 Qxh2 34.Nb5 +.
26 ... Rxa5 27.Qxa5 Rb8!
Subtle move, aimed at 27 to avoid ... Ra8 28.Qxb5!? Qxb5 29.Nxb5 Ra1 30.bxc4 Rxc1 31.Rxc1 Nxc1 32.c5 Kf8 33.c6 Ke7 34.c7 Kd7 35.Nd6 Kxc7 36.Nxf7, where the excess of the figure black will be of little use.
28.Bd2
By human standards play 28.e4!? scary, but the iron one insists on such a decision. His logic is simple: a black horse shown in the field d5, a white elephant given the opportunity to go for a walk.
28 ... Ra8
That such nuances and consists usually the result of the party. Progress before such a move rook allow white to simplify the game, but now this opportunity they no longer have.
29.Qc3
After 29.Qxb5 Qxb5 30.Nxb5 cxb3 31.Bc3 b2 32.Rb1 Rb8 black pawn "b" will create a white big problem.
29 ... Nd5 30.Qc2 Rc8 31.bxc4 bxc4 32.Rb1 Qa6 33.Rb5 g6 34.h3
By pushing the need for vents option 34.Rxd5? Qa1 + - +.
34 ... Qd6 35.Qa2?
Presence passing pawn and a little more activity figures provided black initiative, but by and large, after 35.Ne2 to victory as they were to the moon.
35 ... c3!
It is easy. Pawn moves forward. Defense in white no.
36.Rxd5
And what else? Plays 36.Be1 Nxe3-+, as well as 36.Bc1 Nxc1 37.Qxd5 Qxd5 38.Rxd5 c2-+.
36 ... Qxd5 37.Qxd5 cxd2 38.Qb3 Rc1 + 39.Kh2 d1Q 40.Qb8 + Kg7 41.Qa7 Qg1 + 42.Kg3 Qf2 + 43.Kh2 Rg1 44.Ne6 + Kh6 White resigns (0 -1).
