47...h6+?
The only other reasonable-looking move, 47...Kf7, draws, eg 48.h4 Kg7 49.h5 Kf7 50.h6 Ke7 51.f6+ Ke6. If 48.f6 then any king move draws, eg 48...Ke6 49.Kh6 Kxf6 50.h4 Kf7 51.Kxh7 Kf8 (with an h pawn this is a draw if the white king can be kept off the squares g7 and g8 - for details see https://beauchess.blogspot.com/2020/02/the-power-of-two-squares.html)
The text fails because Black will eventually lose his h pawn without winning White's f pawn (or the f pawn will simply queen).
The game finished:
48.Kf4 Kf6 49.h4 h5 50.Ke4 Ke7 51.Ke5 Kf7 52.f6 Ke8 53.Kf5 Kf7 54.Kg5 Kg8 55.Kxh5 Kh7 56.Kg5 Kg8 57.Kf5 Kf7 58.h5 1-0
