Anti-King chess

Features an anti-king. This piece is in check when not attacked. If a player's anti-king is in check and unable to move to a square attacked by the opponent, the player loses (checkmate). The anti-king cannot capture enemy men, but can capture friendly men. A king may not attack the opponent's anti-king. The anti-king may not check its own king. Other rules the same as in standard chess, including check and checkmate to the regular king. By Peter Aronson (2002).^{[54][55] google, took it from there}
