If Black responds Qxc3, then h8Q wins Black's queen and keeps the black pawn from promoting. If Black moves the King out of check instead, then Qxc8 will lead to White having two queens while Black has one.
Here's mine. It's White's move. Prove that White can mate in two moves, though it's impossible to show the first move that guarantees mate on the next move.

The problem with that answer is that they both have the same first move, so you could show the first move that guarantees mate on the second move. You don't know for sure whether you can capture e.p. anyway.
