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.d4Nf62.c4e63.Nf3d54.Nc3c65.Bg5h66.Bh4dxc47.e4g58.Bg3b59.Be2Bb710.e5This line is rather rare nowadays. It was somewhat popular in 2009-2013 but h4 remains the main line.Nd511.0-0Nxc311...Nd7was Morozevich-Caruana from 2013, whih was won by Black.12.bxc3c513.a4a614.Qb1White will recover his pawn on the queenside, so Black initiates operations on the kingside to undermine White's center. A whole board approach! g415.Nh4cxd416.axb5d317.Bxg4A 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.a518.Bf3Bxf319.Nxf3Qd520.Ra4Attacking the base of a pawn chain is as old of a chess concept as it gets.Nd721.Qa2Black doesn't want to give up his c4 pawn, but maybe he should have.Nb621...Qxb522.Rb1Qd523.Nd2Be724.Qxc4and even though White's position looks a little more pleasant, Black should have enough to keep equal chances.22.Rxa5Rxa523.Qxa5Bc5Black's the own down the pawn now, but with compensation.24.Qa2!Bringing the queen back into the game is excellent.0-025.Qd2Kh726.Re1Be727.Bf4Rg8Black creates his own threats against the White king.28.Kh1Bf829.Be3!Nd730.Bd4Qxb5Black 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.Qf4Bg7?This move is simply bad. The f7 pawn could be sacrificed but not like this.31...Qd532.Qxf7+Rg733.Qf4Bc5with still complicated play.32.Qxf7Qd533.Nd2?!The knight transfers at an inopportune moment.Rf834.Qe7Rf5?!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.Re3Rg536.Rg3Nxe536...Rxg337.hxg3Nb8!was still the way to go.37.Rxg5hxg538.Nxc4!?A brave decision in deep time trouble. Grischuk calculated this very well.Kg639.Qe8+Nf7??39...Kh640.Ne3d2!41.h3!Qb342.Kh2d1Q43.Nxd1Qxd144.Qxe6+is probably a draw.40.Qg8! Black is completely pinned down and cannot defend properly against Qxg7!40.Qg8e541.Nxe5+and no piece can take the e5 pawn.1–0
Caruana, Fabiano 0-1 Jakovenko, Dmitry Caruana was pressing, had the better position throughout the game, and then disaster struck:

35.Qxc3Qd5Still 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.Qc337.dxc4Qa5!And now White cannot defend the rook on e1 and the knight on e4 at the same time.37.Qxc4Qxc438.dxc4Rxe4-+37...cxd3White is simply lost. He cannot deal with all of the incoming threats.38.f3Bxe439.fxe4Rxe440.Rexe4Rxe441.Rf2Re342.Kh2Qe4This swiftly finishes off the game.43.Qc8+Kh744.Rf444.Qf5+Qxf545.Rxf5Re2+46.Kh3Rxb2is simply resignable.44...Re2+45.Kh3Qg2+46.Kg4h5+47.Kxh5Qxg3White is getting mated while Black isn't.0–1
