This can create inequalities in the position. One way to equalize these inequalities is to play a couplet: the players play two games, one each as
Atomic chess king (without the other blowing up), or if one player can occupy the squares next to his king with pieces (or pawns) forcing the opposing king away, it is a win. The variant of atomic chess played at the Internet Chess Club is one that does not enforce check at all, making legal any move, even one leaving the king to be captured directly in the next move. In all variations of atomic chess, a player wins by exploding the king of the opposite color without exploding their own king. This is usually done by capturing a piece on a
