Anti-King Chess

description Anti-King Chess Overview

Anti-King Chess is a fairy-chess variant built around an anti-king, a piece governed by the reverse of the usual check condition. The anti-king must remain under attack, so a move that leaves it unattacked is illegal in the standard form of the variant; this reverses the normal rule that a king may not be in check. The game is for chess-variant players studying how a changed royal-piece rule alters legal moves, threats, and mating patterns.
