  i would play 1.Bf2 here because
  1.h7 Be5
  2.Kxe5 a2
  3.h8Q a1Q+
  to access the long diagonal so now
  i was looking in the line
  1.Bf2 Nf6+
  2.Kf5 Ng4
  3.Kxg4 Be5 and now black has the long
  diagonal but white can play
  3.h7 Nxf2
  4.h8Q
  and also
  1.Bf2 Kc4
  2.Bd4 Nf6+
  3.Kf5 Kxd4
  4.Kxf6 a2
  5.Nb4 a1Q
  6.Nc2+

  I would try 1. Nb4

  1. … Kxb4 (no other move makes progress)
  2. h7 Be5
  3. Be1+ Kc4
  4. Kxe5 a2
  5. Bc3 Kxc3
  6. h8(Q)

  6. … Kc4
  7. Qg8 with a K & Q vs. K & N ending

  6. … Kb3
  7. Ke6 Nc7+ (otherwise the knight is lost after Kd7)
  8. Kd7 Nd5
  9. Qa1 Nb4
  10. c6 Nc2
  11. Qxa2+ Kxa2 and the pawn promotes

  6. … Kc2
  7. Kd5 Nc7+
  8. Kc4 Kb1
  9. Qh1+ Kb2
  10. Qh2+ Kb1
  11. Kd3 and White wins

  4i4mitko got it wrong.

  1.Bf2?! [1.h7? Be5 2.Nb4 Bh8 3.Be1 Nf6+ 4.Kf4 (4.Kf5 Nxh7 5.c6 Nf6 6.c7 Ne8) 4…Nxh7 5.c6 Nf6 6.c7 a2 7.Bc3 Nd5+ 8.Nxd5 Bxc3 9.c8Q a1Q 10.Qb7+ Kc2;
  1…Nf6+ [Black should not play 1…Kc4 2.Bd4+-]
  2.Kf5 Kc4 [Or 2…Nh7 3.Bd4 Kc4 4.Bg7 Kb5 5.c6 Kxa6 6.Kg6 Bf4 7.Kxh7 Kb6 8.Kg6 Bxh6 9.Bxh6 Kxc6=] 3.Kxf6 a2 4.Bd4 Kxd4 5.Nb4 Be5+=

  The solution is : 1.Nb4! Kxb4 2.h7 (2.Be1+ Kc4 3.Bc3 Kxc3 4.h7) 2…Be5 3.Kxe5 a2 4.Be1+ Kb3 5.Bc3! Kxc3 6.h8Q]

  jcheyne got it right.
