The tiebreaker consists of four rapid games of 25 minutes each and if that set is also drawn, a blitz game will decide the match. In both cases Anand would be the favourite not only based on his reputation but his head-to-head record against Topalov in these formats.
Topalov will certainly press for a win, like Anand did in the penultimate game on Sunday. However, the last two games would have given Anand's confidence a boost because with black in Game 10, he played doggedly, throwing the once-bitten Grunfeld back at Topalov...Topalov would like to close the match in regular play because he wouldn't want his opponent to call the shots in the rapid tie-breaker.
So do we expect an all out assault from Topalov? We will see tonight.
