Here is Shredder's automatic analysis of the game. It gets easier to read
after you have loaded it into Shredder again as the lines and
evaluations are displayed in a different color (Mark the game below
and paste it into Shredder).
I have setup Shredder to comment on ever move where Shredder thinks
that a different move than the one played was better by half a pawn.
According to Shredder 33...Qa4, 37...Rbf8 and 43...Kh6 were mistakes
by black. White could have played a better move with 33.b7. (the move
33.Rb1 played by Morozevich was scored with +0.29 pawns after a 13 ply
search where as 33.b7 scored +0.85 pawns.)
