Add white king on a1, and pawns on a2, b2, c2, d2, e2, f2, g2 and h2. The white king couldn't have gotten past the queen unless one of the pawns is removed.

Intention: White is in the middle of castling. Since this move would result in mate, black can't resign under the U.S. rules.

But this is cooked: Black can have the move too, and the last moves were -1. Nf1-g3 h7-h6 -2. g3xQh4.
