Which move?  IE white may simply have a forced win, at least in that
opening, for all we know.  And note that Kh1 vs Kf1 is not a closed issue
yet.  Hsu claimed to have done some analysis with DB2 that suggested that
Kf1 is perfectly ok, but that a later rook move (Ra6 I think) actually allowed
the perpetual to occur.

I don't buy that one.  Until someone shows a move he missed that would have
resulted in
a forced win, or a move he played that resulted in a forced loss while he had a
drawing or
winning move elsewhere...

I am not sure you have to make a mistake to lose with black.  Particularly if
you choose an
opening and had other choices.  Based on that Kramnik certainly made more
mistakes as well,
as one of the first two draws looked winnable, and the two losses were in the
same category.
