Hi
I think black can draw, let's see:
- ... f3
- gxf3 g3
- Ke3 g2
- kf2 g1=Q+
- Kxg1 later, the White king will eat the pawn of g2 with the help of the bishop and will win
But, on the other hand,
- ... f3
- gxf3 gxf3
- Bxf3 Kb6
- Be2 g5
- Ke5 g4
- Kf4 g3
- Kxg3 Kc5
- Kf4 Kb6
- Ke5 Kc5
- Ke6 Kc6
- Ke6 Kc5 The black king stops the white king and the match is draw. The bishop can't do a lot beacause the black pawn is on a black square.
