Nevertheless, after Black lost Pawn it was difficult for him.
Maybe 23... Bd5 was better instead of Bf8 and after 24. Ne4 Qe7 and later try some trick to save the game. White has comfortable Pawn+
edit No2:: ...dxc4 can be criticised: Black should have maintained xd5.
23.Bd5 loses to Qxd5 (though i only saw this after the game, i was expecting ..Bd5 there also..)
I think dxc4 is theory. I've definitely seen Kramnik on the white side of this position. Possibly Aronian also... I seem to remember Kramnik winning a great game in this line, it might have been against Carlsen actually..
