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+ -+
At move 10 I don't think white is in zugzwang,he simply plays Be3,no?
You're on the right track but it needs some finetuning.

Zebano,there ain't no pawn on the h-file.

Ah right,the black king is on c4,I had it on c6.My mistake.
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.

well the simplest way to keep the black king away from c4 is to leave the black pawn there.
1.Bd4 f3!
2.g3! h3
3.Kb4 h2
4.Ka3 h1=q
5.Kb2 =

Yep,that's the solution.Despite it's material advantage Black cannot win.There's only 1 more thing White needs to look out for.For instance
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 🙂
