Subject: first possible example of a Blunder by Kramnik

Go up one level in this thread


Here is a game where Kramnik played black, and he made the same sort of
sacrifice he made against Deep Fritz, but he made it against Anand, and he
got rapped for it.  Crafty says this just drops a piece.  I ran the position
after
Bxf2 to a pretty deep depth and the score didn't change as I even followed the
game for a move or two deeper.  If you let Crafty search for a black move
there, it likes either the rook move as suggested in the annotation, or Nd8
if you let it search longer than one second...  Score after Bxf2 is +3.5, score
after Nd8 is +.5.

That seems to qualify as either a blunder or unsound sac...  your choice.  Here
is the relevant PGN:

[Event "1998.10.23"]
[Site "Tilburg"]
[Date "1998.11.10"]
[Round "2"]
[White "Anand, Viswanathan"]
[WhiteElo "2795"]
[Black "Kramnik"]
[BlackElo "2780"]
[Result "1-0"]
[Annotator "Crafty v19.1"]
{annotating for player Kramnik}
{using a scoring margin of +1.00 pawns.}
{search time limit is 1.00}
