1. d6 is forced, else lose the pawn and the game

1. ... Kc5
2. d7  Bb6+
if 3. Kb8  Be4
   4. Kc8  Bf5 wins

so 3. Kc8  Kc6
   if 4. d8=Q Bb7+
      5. Kb8  Bxd8 wins

   so 4. d8=N+

Without my ending books handy, I'm just winging this response
(I've never seen K+2B vs. K+N). It seems to me that White draws 
this position, but I'm not totally sure. For instance, if 
4. ... Kd6 5. Nb7+ Kc6 6. Nd8+ or 4. ... Kd6 5. Nb7+ K(other than c6) 
6. Kb8 draws. If Black's king goes around to a6 instead, then White's 
king gets away from the edge.
