Eight matches of the fourth round of the World Chess Cup 2013 have started today.
Shakhriyar Mamedyarov defended with the Sicilian Scheveningen and it looked good as he pushed the “liberating” d6-d5, but this only prompted Gata Kamsky to sacrifice a piece and launch a promising assault on the black king.
Black had to find a series of precise moves just to stay in the game, but he underestimated the dangers on the long diagonal and White ruthlessly applied the final blow.
Julio Granda Zuniga stood well with black against Fabiano Caruana until a careless pawn push left him down on material and with a bad position. The Peruvian immediately resigned.
Vladimir Kramnik was well prepared to meet Vassily Ivanchuk’s 5.Bf4 in the Queen’s Gambit and quickly obtained equal position. The pieces were exchanged down to Q+R endgame where the players shuffled for a while until Ivanchuk blundered terribly and allowed the intrusion on the 2nd rank. The game quickly finished in Kramnik’s favour.
Three games were drawn relatively quickly, while Le Quang Liem had a good chance to score against Peter Svidler. However, Le chose the inferior move order and the defending World Cup champion stubbornly resisted until the game was drawn by three-fold repetition.
Alexander Morozevich tried his best against Evgeny Tomashevsky but the game remained equal until draw was signed on move 48.
