That win - a typically delicate operation by Karpov - takes him into the lead, by 21/2-11/2, with two games left to play. White's aggressive opening play was met with calm resolution by Karpov. After 15...Nd6, it looked as though he was heading for equality, but with 21...Qe8 it became clear that he had targeted White's h-pawn as a weaknesses. Anand's 30.a4 was a poor move in a difficult position, giving Karpov a passed pawn that was to win the game for him. In the endgame, White could not stop the a-pawn while holding his K-side together.
