Try: 1.Kc5? f5 2.Kd6 Rf6+ and Black activates his Rook.

Sol: 1.Bf5! gxf5 2.Kc5 f4 3.Kd6 f5 4.Ke6 and Black loses his Rook.

Black wins with 1. ... Rh2# 😛

White wins with 1.g5 and now
a) Kxg5 2.Be4+
b) Kh7 (or Kg7) 2.Rb7+ Kh8 3.Rff7 and after a few black rook checks black gets mated
c) Kh5 2.Rg3! Rh2+ 3.Kxg2 Bxg3+ (hxg3+ then simply Kg2 and later Rb7 wins) 4.Kh3 and later Rb7 forcing the bishop to sacitself.

1.f6 a3 2.Bf7 d3 3.Bg8 d2 4.f7 and Black can't release the stalemate, because 4...Ke7? 5.Kg7 allows White to queen with check.

1.f7+ Kg7 2.f8=Q+ Kxf8 3.Rf1+ and if the king goes to the e-file, then Rfe1 wins. If the king goes the g-file then 4.Rg2+ Rg3 (if the king goes to the h-file then Rh1 with similar follow up on h-file) 5.Rfg1 wins.
