Dramatic day for Topalov in Mexico: after 64 moves of fighting chess, he resigned a drawn position, look:

Magnus has just played 64.Qg6 and Topalov sees no defence against Qh7 and Qh8, but there was a rather simple defence! (if you can't see it, download the game with full analysis of the whole game here: carlstopa.cbv )

However, it'd be completely unfair to claim that Carlsen's victory was undeserved. Watch the first diagram, when he's about to play 48.h6!

Or can you guess his 49th move?, watch:

Magnus now leads the tournament with 3.5/4. Can he win it? I don't think so, although he's already played against Anand, Topalov and Morozevic, 3 players against which I thought he would have scored poorly (2 wins and 1 loss is pretty impressive). I don't know what it is with this kid, I don't think he's that good, he's just... lucky? no, he tries really hard, but sometimes he gets outplayed and his opponents make it look rather easy, like his game against Anand for example. It's gotta be something else... determination, will to win perhaps? talent? who knows...
