White Anatoly Karpov
Black Garry Kaspárov
We can appreciate a Sicilian defense with the variant of the accepted pawn's gambit.
White's position is very passive and allows Black to have a better position to attack
White wants to keep his bishop's attack against the black horse, to keep him neutralized or nailed
These piece changes make White weaken and allow Black to approach the King's flank
Here we see that white has weakened a lot and black lends itself to attack strongly and deadly with his dangerous horses
White leaves, because if they play 41. ♘f1, Black will play ♛x♘ + 42. ♝xf1, ♖xf1 ++
