33...Kd7
The plausible 33...c6?, stopping the white king advancing, seems to only draw. The analysis engines Komodo11.01 and Stockfish11 continue 34.Ke4 Kd7 35.f5 Ke7 36.Kf4 b5 37.g4 hxg4 38.Kxg4 bxa4 39.bxa4 c5 40.fxg6 fxg6 41.Kf4 Ke6 42.Ke4 c4 43.Kd4 c3 44.Kxc3 Kxe5 45.Kc4 Kf4 when both players queen. Note that if Black pushes the b pawn a move earlier, ie 35...b5?, the reply 36.f6 is strong but it is not clear whether it wins.
34.Kd5
Now 34.Ke4 is comfortably met by 34...Ke6.
34...c6+ 35.Kd4 Ke7
An unnecessary refinement as also winning is 35...Ke6 36.Ke4 f6 37.exf6 Kxf6 38.Ke3 Kf5 39.Kf3 b5 etc.
36.Kd3 Ke6 37.Ke4 f6 38.Kd4
We have already seen that exf6 loses.
38...fxe5+ 39.fxe5 Kf5 0-1
