55.Kf4! h6!?
[55...Kxd6?! allows the direct invasion of White's king: 56.Kg5 Ke6 57.Kh6 Kf5 (57...Kf7 58.Kxh7 Kf6 59.g4 Kf7 60.g5+- ) 58.Kxh7 g5 (58...Kg4 59.Kxg6 Kxg3 60.h5+- ) 59.h5 Kg4 60.Kg6+- ]

56.h5?
White violates the important endgame principle "Do not rush". [56.Kg4! wins as proved by Alexander Baburin in Chess Today 3824, e.g. 56...Kxd6 57.h5 gxh5+ (57...g5 58.Kf5 g4 59.Kg6 (59.Kxg4?

But he must still be careful as the edge is very near: 60...Kf6 61.g4 Kg7 62.Kg5 Kh7 63.Kf6 Kh6 64.g5+ Kh7 65.Kf7 Kh8 66.Kg6 Kg8 67.Kh6! (67.Kf6?! Kh7 68.g6+??
