The game started with Naidorf Sicilian, which Hikaru Nakamura himself played earlier against Morozevich. But instead of the English Attack, this time white opted for the good old positional 6.Be2. White obtained the Bishops’ pair and Topalov tried to restrict the light-squared piece with g6-h5 formation. This turned to be a bit too slow because white quickly summoned the pawns on e5 and c5. Black gave up the e5-pawn to set the blockade on d6. The heavy pieces went off and there was an interesting endgame where white had a Bishop and an extra pawn. Black had a good blockading Knight on d6, but the problem was that all of his kinsgide pawns were on the light squares. Nakamura proceeded to exploit the weaknesses, but at one point he missed a quick win with 44.Bxg4. “I am going crazy, this is simply winning,” he shook his head in disbelief. He spent 30 minutes before going in for 50.f5 because he calculated 50…Kg6 and was concerned that black would hold a draw. Topalov quickly replied 50…Nd6 and then white was certain that he was winning. Nakamura pointed that 56…Nb5 was the only move to continue the fighting. Read a full report on the round at Chess Blog.
