Community variant

Crazy Party

All pieces move like a king, except for the queen, which moves only like a king. Pawns promote to a "queen." Also there are drops.

This is a user-catalogued casual variant. Technical details such as board size, FEN, pieces, and hand rules are defined in the Fairy-Stockfish variants.ini block below.
