World No 1 Viswanathan Anand defeated Norwegian Grandmaster Magnus Carlsen in 77 moves, in the third round of the London Chess Classic 2010 on Friday.
Against Carlsen, Anand playing Whites, preferred to open with the King Pawn opening. The Norwegian equalised effortlessly and appeared to have done his homework about the Ruy Lopez game, but he went wrong while attempting to take advantage. Anand capitalised on an ambitious 24th bishop move by Carlsen and threatened the Black King with his queen, rook, knight and bishop.
However, Anand missed a winning continuation on the 33rd and the 36th turns, despite a brilliant knight sacrifice offer on the 29th. However, Carslen’s position was already very difficult to defend. Nevertheless, the Norwegian continued to offer defence before losing on the 77th turn.
Anand and Carlsen have played each other six times this year in the longer version of the game and the former has won two games while four have ended in draws.
In the other games of the third round, Vladimir Kramnik struggled and strived to convert a technically drawn position into victory for 139 moves against Giant killer Luke McShane before bringing about a rare stalemate on board. The other encounters,Michael Adams versus Short and Hikaru Nakamura versus David Howell, also ended in draws.
