This cannot be the correct position if the key is 1.d4.  If you REMOVE the Black
knight from h6, then it's a reasonable (but not very difficult) problem to
solve:

1.d4!

   [1.Ne7? Na7 2.d4 Ke4 3.d5 Ke5 4.Nc6+ Kxd5 5.Nxa7 b5 =]

   [1.Nd6? Na7 2.d4 Kf4 3.Kg2 b5 4.Kf2 b4 5.Ke2 b3 6.Kd2 b2
    7.Kc2 b1Q+ 8.Kxb1 Ke3 =]

1...Ke4 2.Nd6+

   [2.Ne7? transposes to the first note above, and only draws.]

2...Nxd6 3.a7 +-
