a position inspired from a recent game [I just removed one white pawn to balance it]. Two main ways to win, which had a beautiful idea. The puzzle is for the fastest way for white...

1.a5 wins very easily. 1.b5 might be your idea, then sac on b6 and Kd4 zugzwang both ensure that the king penetrates

hi simaginfan!

1.a5 was my thought while playing it too, though I didn't manage to foresee all moves then. I saw 1.b5 afterwards, while toying on the analysis board

Well, with a5 you don't need to calculate much. The king can enter, and bishop moves force zugzwang.

I have found two nice ways to not win: 1.Bc7!! and 1.Bb8!!

I'm afraid that every other move wins within a few moves.

true. the position doesn't have exactly one unique solution, as the puzzles should have. The point I saw was the use of the B, a necessary sacrifice at one unique spot, since the rest opponent's pawns are on the opposite color
