Black managed to exchange the queenside pawns which improves her drawing chances. But Black still has to fight and in "Fundamental Chess Endgames" Karsten Müller claims that knight endings with four against three pawns on one wing are almost always won for the side with the extra-pawn. 42...g6 43.Nc4 Kg7 44.Kf3 Nc5 45.e4 Ne6 46.Ke3 Kf6 47.f4 Nc7 48.Ne5 Nb5 49.Kd3 Ke6 50.Nf3 Ke7 Exchanging knights loses immediately: 50...f6?? 51.Nd4+ 51.Nd4 Nc7 52.Ke3 Na6 53.f5 gxf5 53...Kf6 54.Kf4 g5+ 55.Ke3 Nb4 56.h4 g4 57.Nb5 57.Ne2? yields nothing Ke5 58.Nf4 Nc2+ 57...Ke5 58.Na3 Kf6 59.Nc4 and the advance of the e-pawn secures White the win. 54.Nxf5+ Kf6 55.Kf4 Nc5 56.e5+ Kg6 57.Ne7+ A shorter way to win was 57.Nh4+ Kg7 58.Kf5 Ne6 59.Nf3+- 57...Kg7 58.Kf5 Nd3 58...Ne6!? may have been more stubborn. 59.Nd5 Nc5 60.h4 Kh6 61.Nf6 Ne6 62.Ne8 Nc5 63.Nd6 Kg7 64.Ne8+ Kh6 65.Nd6 Kg7 66.Kg5 Nd7 67.Nc4 f6+ 68.exf6+ Nxf6 69.Nd6 1–0
