Karpov won the game after 47...Rc4 48.h4 Rd4 49.Rf6+ Kg7 50.Ra6 Kf7 51.h5(deep thought finally realised here that it was worse) gxh5+ 52.Kf5 Kg7 53.Ra7+ Kf8 54.e6 Re4 55.Rd7 Rc4 56.Rxd5 h4 57.Rd3 Ke7 58.Rd7+ Kf8 59.Rh7 h5 60.Ke5 h3 61.f5 Kg8 62.Rxh5 a3 63.Rxh3 a2 64.Ra3 Rc5+ 65.Kf6 I read this game in the book of grandmaster raymond keene and david levy:How to beat your chess computer In the post mortem Karpov said he thought 47...g5 could still draw.
