Cheshire Cat Chess is a chess variant created by Vernon Rylands Parton in 1970. The idea is based on a fictional cat appearing in Lewis Carroll's Alice's Adventures in Wonderland, which appears and disappears at will.
The game is played with standard Chess rules but there are two important changes:
When a pieces moves to another square, the former square disappears and no piece can move to it (but pieces can move or give a check over disappeared squares).
When a king moves for the first time, it can move as a queen (it also means that there is no castling in this game).
