I'm not quite sure if chessmaster is right about 'the only meaningful error'. I heard that ..cxd5 was a huge positional blunder, and that ..c6 and ..Bg4 were a bit dubious. 

I'm wondering if the line suggested by CMX leads to anything but a win for white as  well :). That would have surprised Carlsen.

38... Bc5+ doesn't remove the threat on black's bishop and knight. It simply postpones it. I have no idea why I posted this.
