Cats love chess, especially since the pieces on the chessboard are just begging to be knocked over and flung across the room. Yet if you’re an avid chess player and find yourself a little bored with traditional chess, you may want to explore Cheshire Cat Chess.
The basic idea behind Cheshire Cat Chess is to make an ordinary chess game a little more interesting. In Cheshire Cat Chess, every time a piece vacates a square, the square disappears. A piece cannot (obviously) move to a disappeared square, but pieces may move over disappeared squares, and also give check over disappeared squares. The first time a king moves, it may move as a queen. Note that castling is impossible.
