Only one possible solution - I assume this has been already solved:
pxp ep kxa5
rxa7 mate
pxp ep kxa5
rxa7 mate

It has been solved... And your answer is mostly right...
Kxa5 is not possible. The pawn at a5 is the one that was used for the ep so the move is Ka5 not kxa5. So as I said its mostly right
I know I am being picky, but peoples misunderstanding of en passant is annoying me

Do I have to be a paying member? That's pretty annoying.

2... Kb5 is not a legal move because the Bishop is now at a4 and attacks b5.xJuggleboy said:
2... KxB is not a legal move because the King is now at c4, and the Bishop at a4, two squares away.
If, however, you mean 1... KxB, this case was handled by quark in message #40 of this thread.
