50. Kf6? Kd6! Drawn by the 50 move rule!
play all play one stop play next play all
White's pre-diagram move couldn't have been a capture, so the 50-move counter has already been set to 1. Thus, White must play 50. Kxf5 in order to reset the counter, or else Black will draw.

Henrik Juel: 3 and 5 captures by white and black pawns are obvious, leaving [Ph2,Ph7], so the remaining white capture was hxg (with promotions on g8 and h1) or officerxPh (with promotion on h8) (2022-11-05)
