Susan Polgar is regularly stunned and shocked when it comes to chess events and moves - but even she might have to reach for the thesaurus to express her amazement at this one.
In the diagram position it's black, Kramnik, to move, in game 2 of his match against Fritz from today. Now it doesn't matter how centralised you are, whether you'll be better in the endgame after a queen exchange, nor whether your bishop is better than the knight, or how quick you can make a passed pawn - not when your opponent threatens mate in one.
So, here are the moves of the game, if you can bare to look. The diagram is at move number 34:
