In Response To: OT: Promotion in chess (Timothy Chow)

Raymond Smullyan carries the conundrum even further by supposing that you amend the rules of chess to allow promotion to a piece of your opponent's color.

I will call such a promotion "counterpromotion." Do you have an example of a position where you need to counterpromote a pawn to win/draw a game? Assume all other rules of chess are unmodified.
