Panic Chess is a chess variant where pieces are too panicked to listen carefully to your commands. The piece you selected to move will try to capture a randomly chosen opponent piece in its range. If capturing is impossible, it will choose a random non-capture move. The king will not step on a square attacked by the opponent unless one of the two exceptions applies: The king will not avoid danger when he can capture or when left alone without any other pieces on board. Pawns will undergo a random promotion upon achieving the last rank. You win by capturing the opponent king. You may claim a draw unilaterally after 50 moves without a capture.
