Well, the shortest possible checkmate is two moves -- the Fool's Mate. But for that you'd have to move G and H pawns, so you've avoided that at least. Anyway, beating you that quickly might be educational, but it's not necessarily that fun.

[Freddie moves one of his own pawns forward two squares, then taps the pawn she moved.]

Remember, you can move a pawn two squares when it's in its starting position.
