London Chess Classic – Carlsen, Anand, McShane lead
The game between the two leaders was a tough trial for the tournament's dark horse, McShane, who found himself in a difficult position, in danger of losing. Adams and Kramnik had a hard game before they also drew. Short played a rare offshoot of the Marshall Attack against Nakamura which backfired, while Carlsen outplayed Howell in a simplified middlegame and won.
