Now watch out for this variation: on 61.Rc3!, if Topalov would play 61...b2?? 62.Rxc5! b1=Q?
For this reason Topalov must answer 61...Rd4, and the rook ending will be quite drawish.
Sven
nice mating-trap indeed after 61. ... b2?, but I am sure Topalov will spot that.

Why should he miss that, if even I see it?
