i think you mean
1.Bd4 h3?
2.f3+gxf3
3.gxh3! any
4.Bf2 +-
More interesting of course is
1.Bd4 f3!
2.g3!? (2.gxf3+ Kxf3 3.Kxc4 h3 4.Be5 Kxf2 5.Kd3 g3 6.c4 h2 7.c3 h1=Q -+)
2...h3
3.Kxc4 h2
4.Kb3 h1=q
5.Kb2 Qe1
6.Bc5 Kd5
7.Bb6 Kc4
8.Bd4 Qd2!! (triangulation for zugzwang)
9.Kb1 (Ka2 Qc1 any Qxc2+ and wins.)
9...Qd1+
10.Kb2 Qe1 (zugzwang)
11.Ka2 Qc1
12.any Qxc2+ -+
You're on the right track but it needs some finetuning.
Zebano,there ain't no pawn on the h-file.

10.Be3 Qxc3+ 11.any Qxe3 12.fxe3 f2 -+
Well,then you know this doesn't work cause white loses while he can draw.
But you have the right idea,just white needs to build a stronger fortress to hide in.

1.Bd4 f3!
2.g3! h3
3.Kb4 h2
4.Ka3 h1=q
5.Kb2 =
5.Kb2,Qh6
6.Kb1,Qd2
7.Kb2,Qxd4 (knowing it's a draw Black could try this hoping for a white slip in the endgame)
8.cxd4,Kxd4
9.Kb1 (avoiding the last pitfall 9.Kc1?? with a black win!)
But that's just basic endgame play.Not really relevant to the puzzle.
Well done 🙂
