This is one of the most unusual (or shocking) round I have ever witnessed in a long time. Aronian, in a dead drawn position, managed to find the only losing plan. Magnus, who was worse throughout most of the game, had drawing chances. But he did not find the right continuation and Ivanchuk managed not to blunder in time pressure to win. All of a sudden, Kramnik is now in 1st place with just two rounds to go. This is pretty incredible. What most people thought was a two horse race in the first half, turns out to be Carlsen chasing Kramnik.
