Just two moves later, Anand made a slight inaccuracy that allowed the centre to be dissolved.

In the post game conference Anand candidly admitted he missed a move. "I should have at least thought about it," he said. Once the centre was opened, Caruana had no problems and subsequent exchanges led to a drawn opposite coloured Bishops endgame where the peace was signed after 40 moves. Naiditsch pushed hard for a victory and his efforts were rewarded when Adams cracked under pressure. The Nimzo Indian by the English met with some classical response and it was a tense affair after Naiditsch gave up his queen side pawns for an ambitious attack. Adams decided to part with a rook for knight but his position remained difficult to defend. After nearly seven hours, the German romped home. Fridman and Meier played out a draw through repetition of moves from an irregular queen pawn game. The shortest game of the day lasted just 26 moves. Results round 2: V Anand (Ind, 1) drew with Fabiano Caruana (Ita, 1.5); Arkadij Naiditsch (Ger, 1.5) beat Michael Adams (Eng, 0.5); Daniel Fridman (Ger, 1) drew with Georg Meier (Ger, 0.5).
