Carlsen’s game was a rather strange one. He didn’t like his position from the opening, but at some point it seemed clear that the game would end in a draw. An endgame with equal pawns and opposite colored bishops seemed to seal the deal. However, the World Champion was rather careless and lost a pawn. Grischuk tortured Carlsen for a long time, until eventually (6.5 hours later) Carlsen blundered.
