Since there isn't much intrest I'll give you the first move and objective.

White draws after 1.Ke4 1.Ke4 f2 2.b7! f1=Q 3.bxa8=q Qg2+! 4.Ke3!! Qxa8 5.d5! and now white simply maintains the opposition.
i missed 5.d5 the first time around and then i missed 4.Ke3 the second time around.

i missed 5.d5 the first time around and then i missed 4.Ke3 the second time around. Exactly!It's a study by Somov-Nasimovich 1938.

[fen]8/6B1/8/2K5/2p1kppp/2P5/2P2PP1/8 w - - 0 1[/fen] Clearly white must address the threat of h3
The only way i can see to do that is
1. Bd4 h3
2. f3+ gxf3
3. gxf3+ Kxf3
4. Bf4

9...Qd1+
10.Kb2 Qe1 (zugzwang)
