To Veselin Topalov, naturally. No matter what Vladimir Kramnik says in this interview pretending that he isn't affected by Topalov over the board, his fairly poor results against him since their world championship match tell a different story. Kramnik used to own him, but now, no matter how bad Topalov's form is in any given event, he is even looking like a favorite against him.
With the loss, the Norway Chess tournament now has three co-leaders: Kramnik, Magnus Carlsen (who drew a Berlin ending with Black against Sergey Karjakin), and Fabiano Caruana (who drew with Black against Simen Agdestein). Their draws were "clean" - no one had a serious advantage at any point, and the same goes for the other two draws. Levon Aronian had White against Anish Giri, but ultimately had the (not-too-difficult) task of forcing a draw while a pawn down. Finally, Alexander Grischuk and Peter Svidler drew quickly.
The games are here (without notes), and tomorrow's round 7 pairings follow:
