Karpov is not what he was just a few short years ago. After 63 moves in the actual game: 5b2/6p1/4k2p/p4p1P/3P4/1P2NKP1/5P2/8 w - - 2 64 I think Karpov's 64. g4 is not a good move (I do not pretend to have better endgame technique than Karpov, but it seems he badly misplayed this one). Bringing the king to the queenside looks like the right plan to me. For example 64. Nc4 Bb5 65. Ke3 Kd5 66. Kd3 followed by Ne3. Then the plan is to keep under attack the f5-pawn with the knigth and threaten the a5-pawn with the king. White should not worry about exchanging the a5-pawn for the b3-pawn, as N vs B endings with all the pawns in one side are in general favorable to the side with the knigth. White can safely exchange the f5-pawn for the d4-pawn, as long as it allows him to put all his pawns in white squares. José.
