1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5 7.Nb3 Be6 8.f3 Nbd7 9.g4 Nb6
A fashinable variation. Threatening an advance of d6-d5 Black forces out White to determine the position of pawn on the King's side.

10.g5 Nh5 11.Qd2 Be7 12.0-0-0 0-0 13.Kb1 Rc8 14.Rg1 g6 15.Qf2 Nc4 16.Bxc4 Rxc4
also was checked many times at the highest level of chessplayers 16...Bxc4 17.Na4!?.

A new move. After 17.Nd5 Bxd5 18.Rxd5 b5 as was played formerly in a number of games White is difficult to find a lucky employment of the Knight 'b3', while Black retains possibilities to get play on the King's side by way of f7-f6.

17...b5 18.Nd5 Bxd5 19.exd5
Now when a black Pawn 'b' moved from its place White preferred to take at d5 with 'e' Pawn, in order to use weakning c6 square in future.

19...Nf4 20.Bxf4 Rxf4

The position is more or less determined. All Black's pieces are in fighting. Even formally bad 'e7' Bishop has fomed the work and makes pressure on White's 'g5' Pawn.

After this move White is to sacrifice a Pawn. It is more natural to move 21.h4 immediately, and if 21...f6 (21...e4?! at once is not good because of 22.Re3!), then after approximate 22.gxf6 Bxf6 23.h5 e4 24.Rdd1 Rxf3 25.Qe2 Qe8 26.hxg6 hxg6 27.Rg4 Qe5 28.Nd4 Qh5 29.Rxe4 (loses 29.Qxe4? because of 29...Rg3!-+) Bxd4 30.Rexd4= balance of power is not broken.

21...Rf5 22.h4 f6 23.Qh3
In case of 23.gxf6 Bxf6 24.Rh1 Rh5! White had to lose the Pawn in the worst condition.

23...fxg5 24.h5
Thus, White succeeded in muzzling the Bishop in the form of 'g5' Pawn and thereby in getting a certain compensation for minimal material losses.

24...gxh5 25.Qxh5 Qe8 26.Qh3 Qf7 27.Nd2 Kh8 28.a3 Bd8 29.Rh1 Qg6 30.Rc3
Having a pawn less White does not want to stand still and direct its Rook to 'c6' square.

30...Rf4 31.Rc6 Rh4 32.Qg2

Possible, beginning from after the tranfer of his Rook at 'c6' Sergey Karjakin understimated the power of this Black's move. Exchage of castle quite suited the White 32...Rxh1+ 33.Qxh1, as in that case Black cannot create real threats, but the problems of defending the Queen's side remain.

It loses speedily, but what was to be done? After 33.Rxh4 gxh4 the passed pawn 'h4' is very dangerous, and 'c6' Castle cannot obviously help the white Queen. After approximate 34.Ne4 h3 35.Qh2 Be7 36.Rxa6 Rxf3 37.Ra8+ (if 37.Nd2, all possible couriterplay is stopped with 37...Rf8-+) 37...Bf8!-+ result of the game were also predetermined.

Threatens to move Rh4-h2 winning a Knight, and the Knight cannot leave its 'd2' field because of the loss of 'f3' Pawn.

34.Rg1 Rh2 35.Qxg4 Rxd2 36.Qd7
To 36.Rxd6 most simple is проще всего 36...Rd1+ 37.Rxd1 Qxd6-+.

36...Rxd5 37.Rc8 Qf6 38.Ra8 Rd2 39.Ra7 Rh2 40.Rg7 Qh6 41.Rf7 Rg8 42.Ka2 Qg6 43.Qc6 Qe6+ 44.b3 Qg6 45.Kb2 Bb6 White resigned. (0-1)
