Now White is ready to enter Black's position on the queenside, while a black attack on the other side has lost considerable sting now the light-squared bishop from c8 has disappeared. White converted his big advantage.

Black targets the a4-pawn. Well, it seems that Kasparov has said that in general, a knight on f5 is worth a pawn. So,

Making way for the knight, en route to f5!

27...Qxa4 28.Nd4 Qb4 29.Rc3 a4 30.Nf5

The killer knight.

Now it is over. White took on c4 and won after a few more moves.

You guessed it!

The pawn structure certainly will not bother White in the endgame after 6...dxc5 7.Qxd8+ Kxd8 8.Be3 e6 9.Nc3 Nf6 10.0-0-0 Nfd7 11.f4.

Yet by avoiding the endgame Black soon lands his queen in trouble.

8...Nd7 should have been played.

White is virtually winning already.
