Svidler in trouble after day one of the quarter finals

Peter Svidler ended the first day of the quarter finals in the worst state after losing with the white pieces against Vladimir Malakhov. Shakhriyar Mamedyarov will at least have the white pieces against Sergey Karjakin in a must win game. The other two games were drawn. Boris Gelfand against Dmitry Jakovenko was a quick draw, Ruslan Ponomariov against Vugar Gashimov after a prolonged struggle.

Boris Gelfand

Final Position

Ruslan Ponomariov against Vugar Gashimov was a complicated Modern Benoni, white could have grabbed the exchange at one point and that may have been the best option. As it was the players repeated moves around the first time control.

Peter Svidler's choice of variation in the Slav Defence never looked that impressive. He did go for a kingside attack but black had no difficulty repulsing the attack. Svidler continued to attack instead of allowing perpetual check and his position immediately collapsed. This kind of sudden collapse is oddly prevalant in Svidler's games.

Peter Svidler

Position after 24...Qd6

White's had a go at the king, now is the time to bail out.

25.Ba2??

I'm not sure what Svidler missed but now the game is over.

[25.f6 Bxf6 (25...Bh8 26.g5 Nbd7 27.Ba2) 26.Qxf6 Qg3+ with perpetual is probably the correct finish to the game.]

Sergey Karjakin against Shakhriyar Mamedyarov was a complex struggle in an Open Ruy Lopez. Mamedyarov was pushed back after starting with an optically attractive position. Mamedyarov was only a few moves from a draw when he blundered, Karjakin missed the best and then Mamedyarov missed another opportunity to draw after which the game was over.

Optically this position looks good for black, but in fact he's about to get pushed back.
