Alice Chess

Alice Chess is a chess variant played using two chess boards, A and B. It's named after the main character "Alice" in Lewis Carroll's book Through the Looking-Glass (you remember?), and was invented by V. R. Parton in 1953.

All pieces move as in standard chess, except that the en passant capture is abolished. The normal array is on board A; board B starts empty. In turn, each player makes a single move on either board following these three rules:
1. A move must be legal on the board where it is played.
2. A move can only be made if its destination square on the other board is vacant.
3. After moving, the piece is transferred to the corresponding square on the other board.

If you like to read more about Alice Chess, here are links to two articles: The Chess Variant Pages,
George Jelliss.

You can play Alice Chess online and against computer software &mdash see the first of the links I just mentioned. Of course, there are also chess compositions with the condition Alice Chess.

"A" or "B" behind a move indicates to which board the respective piece is transferred. After castling, both king and rook go to the other board.
