 The clash between Sergey Karjakin and Fabiano Caruana was more interesting, because Karjakin put some pressure on his opponent but was not able to find a clear win.The decisive games were played on the lower boards.On board four, Alexander Grischuk managed to score a full point with the Black pieces against Ray Robson after the American played too passively in the time trouble, making a miscalculation on move 38 when he decided to liquidate the opponent's knight and allowed Grischuk to get a winning position with a passed e-pawn.
