Anand played the Brayer defense in the Ruy Lopez openingand after equalizing the Indian ace was simply superb on theboard. When many believed to a be a drawn endgame, Anandcontinued to fight for a victory giving up a rook for aBishop.
The game could have been drawn with precise play butSmeets allowed Anand to march ahead with his pawn after ablunder on the 57th move. By the time the Dutchman, who had afine start, gave back his extra material, Anand had knockeddown three pawns and it was all over in quick time.
Carlsen''s perseverance paid off in his game against L''Amiwho defended a worse position well for the major part of thegame. The world number one Norwegian went for a double edgedendgame and won a pawn but the technicalities were far fromeasy as L''Ami matched him move for move.
