Sorry, in game 2 I didn´t saw Kramnik having opening problems or being outplayed by Topalov.
In fact, Black´s position around move 20 seems pretty okay, Kramnik had equalized in a sharp position.
Probably Kramnik didn´t want to go for a drawish line and overestimated his winning chances!
And so he took the a4 pawn while it might have been better to play Rec8 first. I also interpret 31...Bxf8(??) instead of 31...Kxf8
as playing for a win instead of taking a draw. (Of course I cannot say if 31...Kxf8 would really draw, the play remains really difficult).
Okay, later on Kramnik terribly blundered. But so did Topalov, too.
Topalov made the first mistake (!! to let Kramnik equalize out of the opening !!) and the last deciding one.
Inbetween he had a winning position for some moves, but I do not think that Topalov deserved the win more than Kramnik.
I see no reason for Kramnik to abandon the Open Slav. I expect a further Catalan in game 3
and a further Open Slav in game 4 (with Topalov deviating first!). With Kramnik scoring 1.5 points out of these!
From then on Topalov will switch to Modern Benoni and 1.e4 .
But it won´t help him. Kramnik will win the match with game 10 (or even earlier).
