Khanty Rd8: More mistakes!

by Alejandro Ramirez
5/22/2015 – Big mistakes today changed the standings significantly. Caruana lost to Jakovenko: the Italian player was pushing for a significant amount of time and then out of nowhere he blundered heavily! Jakovenko took advantage of his chances and won. Grischuk beat Karjakin in a very complex game marked by a last-minute Karjakin blunder. Finally Nakamura's game was unpredictable!

Daniel King shows the highlights of round 8

Gelfand, Boris 1-0 Svidler, Peter
Gelfand's preparation gave him a nice edge in the Russian variation of the Grunfeld. His pair of bishop advantage coupled with the passed a-pawn was annoying to deal with and finally helped Gelfand to win.

Svidler's Grunfeld was in serious danger today

Tomashevsky, Evgeny ½-½ Dominguez, Leinier
Tomashevsky won two pawns in the opening, but Dominguez had typical Grunfeld counterplay. The Russian player decided to sacrifice a pawn to ease the pressure, giving the unusual material balance of a minor piece and two pawns against a rook. Dominguez thought he was worse and sacrificed the exchange back for a pawn, hoping to draw the opposite colored bishop endgame - which he was lucky enough to do.

Evgeny Tomashevsky missed a number of good chances

Vachier-Lagrave, Maxime ½-½ Giri, Anish
MVL at least didn't lose again, but he never managed to put Giri in any real problems. The Dutch player sacrificed a pawn that he was very clearly going to get back at some point.

MVL dropped down to place 29 in the World

Jobava, Baadur  0-1 Nakamura, Hikaru
A hard game to understand. Nakamura was better the whole game and at some point he was even up three pawns. However he botched it up and Jobava had good chances to hold. He inexplicably, however, went for a completely lost rook and pawn endgame that Nakamura finally managed to convert.

And push he did, Jobava made it easy by eliminating one of the g-pawns and transposing into a lost endgame

Nakamura was winning, then not, then Jobava blundered

Grischuk, Alexander 1-0 Karjakin, Sergey

1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 c6 5.Bg5 h6 6.Bh4 dxc4 7.e4 g5 8.Bg3 b5 9.Be2 Bb7 10.e5 This line is rather rare nowadays. It was somewhat popular in 2009-2013 but h4 remains the main line. Nd5 11.0-0 Nxc3 11...Nd7 was Morozevich-Caruana from 2013, whih was won by Black. 12.bxc3 c5 13.a4 a6 14.Qb1 White will recover his pawn on the queenside, so Black initiates operations on the kingside to undermine White's center. A whole board approach! g4 15.Nh4 cxd4 16.axb5 d3 17.Bxg4 A very strange position. White has many pluses: better development, safer king. However Black's passed pawn on d3 cannot be underestimated. It won't queen soon, but it heavily restricts White's pieces. a5 18.Bf3 Bxf3 19.Nxf3 Qd5 20.Ra4 Attacking the base of a pawn chain is as old of a chess concept as it gets. Nd7 21.Qa2 Black doesn't want to give up his c4 pawn, but maybe he should have. Nb6 21...Qxb5 22.Rb1 Qd5 23.Nd2 Be7 24.Qxc4 and even though White's position looks a little more pleasant, Black should have enough to keep equal chances. 22.Rxa5 Rxa5 23.Qxa5 Bc5 Black's the own down the pawn now, but with compensation. 24.Qa2! Bringing the queen back into the game is excellent. 0-0 25.Qd2 Kh7 26.Re1 Be7 27.Bf4 Rg8 Black creates his own threats against the White king. 28.Kh1 Bf8 29.Be3! Nd7 30.Bd4 Qxb5 Black recovered his pawn but White has managed to bring his bishop to a far more active square. The powerful passed pawn is compensated by the weakness of the Black king. 31.Qf4 Bg7? This move is simply bad. The f7 pawn could be sacrificed but not like this. 31...Qd5 32.Qxf7+ Rg7 33.Qf4 Bc5 with still complicated play. 32.Qxf7 Qd5 33.Nd2?! The knight transfers at an inopportune moment. Rf8 34.Qe7 Rf5?! 34...Nb8! Was the surprising and powerful move here. The point is that Nc6 and Nxd4 is a very real and hard to stop threat. 35.Re3 Rg5 36.Rg3 Nxe5 36...Rxg3 37.hxg3 Nb8! was still the way to go. 37.Rxg5 hxg5 38.Nxc4!? A brave decision in deep time trouble. Grischuk calculated this very well. Kg6 39.Qe8+ Nf7?? 39...Kh6 40.Ne3 d2! 41.h3! Qb3 42.Kh2 d1Q 43.Nxd1 Qxd1 44.Qxe6+ is probably a draw. 40.Qg8! Black is completely pinned down and cannot defend properly against Qxg7! 40.Qg8 e5 41.Nxe5+ and no piece can take the e5 pawn. 1–0

One of many Russian duels

Caruana, Fabiano 0-1 Jakovenko, Dmitry
Caruana was pressing, had the better position throughout the game, and then disaster struck:

35.Qxc3 Qd5 Still a complicated position. White is up a pawn but Black has all the activity. Chances should be around equal. 36.Qb3? A big blunder! 36.a3= 36...c4! Excellent. 37.Qc3 37.dxc4 Qa5! And now White cannot defend the rook on e1 and the knight on e4 at the same time. 37.Qxc4 Qxc4 38.dxc4 Rxe4-+ 37...cxd3 White is simply lost. He cannot deal with all of the incoming threats. 38.f3 Bxe4 39.fxe4 Rxe4 40.Rexe4 Rxe4 41.Rf2 Re3 42.Kh2 Qe4 This swiftly finishes off the game. 43.Qc8+ Kh7 44.Rf4 44.Qf5+ Qxf5 45.Rxf5 Re2+ 46.Kh3 Rxb2 is simply resignable. 44...Re2+ 45.Kh3 Qg2+ 46.Kg4 h5+ 47.Kxh5 Qxg3 White is getting mated while Black isn't. 0–1
