With Rook and Knight against two Rooks and in serious time trouble, Howell seemed to be fighting a lost cause but the Knight - combined with the British Champion's remarkable powers of concentration and determination - managed to cause enough technical problems to hold the draw.
Although Carlsen will clearly feel he should have won, the draw keeps the tournament alive. With three points for a win, starting with three straight victories would have given the World No.1 an almost unbeatable advantage.
Meanwhile, Kramnik played very powerfully to win his second game of the event. His Black Knights sealed the fate of McShane's King.
Nakamura and Short drew (another Rook ending) and Adams played the Marshall Attack against Ni Hua. As so often in that opening, a sharp-looking position fizzled out into a draw.
