Interesting puzzle. As a minor aside, I'm thinking the position could never occur in an actual game.

What do you mean by 'actual game'? The position can certainly be obtained via legal moves.

The posters so far forgot to mention/show the condition (proof is easy) for the solution: blacks last move MUST HAVE BEEN b7-b5.

I don't think you're correct there actually. Blacks black bishop would have had to move from f8-d6-b8, but it can't as there is a black pawn on c7....

Edit:ACtually i'm wrong, it could get to b8 via the a-file.

Sorry, I stand corrected. I missed the a5+, Ka7, Kc5 possibility.
