[After 68.Nf5! the knight wins the c-pawn first and is just in time on the kingside: 68...Kc5 (68...a4 69.Nd6+ Kc5 70.Nxc4+- ) 69.Ne3 a4 70.Nxc4 Kd5 71.Ne3+ Ke4 72.Nf5 Kf4 73.Nh6+- ; After 68.Nc8? the knight is dominated by 68...Kc5= den Springer.]

68...a4 69.Nc7+
[69.Kd4 does not help as White's blockading forces must remain on the queenside: 69...a3 70.Nc3+ Kb4 71.Na2+ Kb3 72.Nc3 Kb4= ]

69...Kc5 70.Ne6+ Kd5 71.Nxg5 a3 72.Nf3 Ke4 73.g5 Kf5 74.Kc2
To win White must change the roles of his pieces: the knight should stop the pawns and act as a source of tempi and the king must support the g-pawn. But this can not be accomplished.
