In game ten Topalov played the Catalan again, and Kramnik again reached a better position. I won't do analysis of concrete moves today - there is an excellent analysis of the game at chesspro.ru, where Mikhail Golubev replaces Peter Svidler, who is now playing at the European Club Cup. I think Topalov is somehow playing the Catalan when he wants to draw, and the Slav when he wants to win with Black.
Game twelve is the last game in the match, and Kramnik has White. While I generally think Topalov should play for a draw and not risk too much, I can only recommend the Slav to him.
Out of Topalov's four games with Black so far (not counting the forfeit), he played the Slav once, and the Catalan three times. Topalov has scored one point out of the Slav game, and half a point ouf of the three Catalan games together. He also had a good position out of the opening in the Slav game, but three times a worse position in the Catalan games. Enough said.
I hope for an exciting game twelve and am not thinking about the tie breaks yet - after all we have seen already five decisive games in the match. We haven't seen so many decisive games in a world championship match for some time.
