How to play
Alice Chess

Named after Alice in Lewis Carroll's work Through the Looking-Glass. Chess on two boards with pieces moved between the boards.

Alice Chess is played with one set over two boards. As pieces are moved, they transfer to the mirror board.

Starting Position

One board is set up as normal, with the second board remaining empty.
Board is interactive - make a move

Moves of the Pieces

Pieces move as normal subject to the square on the mirror board being empty. Pieces are captured on the same board

White can make a capture
Board is interactive - make a move

Pieces can be played on either board .

Pawn Promotion

Normal promotion rules, but only when a square is available on the mirror board for the promoted piece to be placed.

Castling

Castling can only be completed if space exists on both board. That is, the empty squares between the king and rook must be empty on the mirror board too.

Castling is available as the other board is clear
Board is interactive - make a move

Kingside and queenside castling blocked by pieces on the mirror board.

Castling is blocked queenside - you cannot castle onto the black bishop.
Board is interactive - make a move
Castling is blocked kingside - the king can't castle past the black knight
Board is interactive - make a move
You cannot castle through check on either board
Board is interactive - make a move
En passant is not available in Alice Chess

¹ Support is under consideration and may be implemented for this variant.

Check and Checkmate

Check and checkmate is possible on either board. A king in check cannot escape by moving to the other board.

Checkmate - black is in check and any blocking movement would result in that piece being transferred to the other board leaving the king still under attack.
Board is interactive - make a move
Just Check - black can escape check by moving to a square that is not under attack on either board.
Board is interactive - make a move
Checkmate - black is now unable to escape check on board A, as moving to F7 would result in check on board B when it is transferred over.
Board is interactive - make a move

Stalemate conditions remain the same as Standard Chess.

Draw conditions remain the same as Standard Chess.

Winning

Checkmate your opponent on either of the boards.
