I found this hilarious problem and hope people will have fun solving it:
Niels Hoeg, Skakbladet 1907
[FEN "8/8/6p1/5pP1/5P1K/5PpP/4p2p/2Q2Bkr w - - 0 1"]
White to end the game in two moves.
In this case, that means that white plays moves so that, no matter what black moves, the game is finished after black's second move at the latest.
