Swapping Kings: When the side on-move checks the opposite King, the Kings change places.

This is known as the “swap”. A swap is mandatory. The legality of any checking move is evaluated after the swap, except in certain cases involving castling. Castling out-of–check is illegal (wKe1 wRh1 bKe8 bBa5, 1.0-0??). Castling through check is illegal (wKe1 wRh1 bKf8 bBa5, 1.0-0??). Castling into-check is legal (WKe1 WRh1 BKf8 BBa7, 1.0-0!) A King swapped back to its game-array square is considered “reborn” and is eligible to castle.

Koko Chess (Contact Chess): a move is legal only if the arrival square is adjacent to any piece, this applies also to the capture of king.

Nightrider: a rider moving along any straight line of S moves.

Rook Locust: a piece which moves only to capture on Rook lines. After the capture it lands on the next square.
