A drawn position.
A viable defense-plan for black works as follows:
-If the black king is on b8 he goes to one of the squares a8,c8 or c7.
If he cant move there, the game is an immediate draw under any circumstances.
-If the king is on a8, c8 or c7 he moves to c7. If he cant move there, the game
is draw immediately.

It is obvious that white cant make progress, if he cant take the pawn a7.
He cant move there, if black stays in his fortress a8,b8,c8,c7.
