Move Rules
Pieces move the same as they do in standard chess, but a piece transfers at the completion of its move to the opposite board. This simple change has dramatic impact on gameplay.
At the beginning of the game, pieces start in their normal positions on board A, while board B starts empty. After each move is made on a given board, the moved piece is transferred (goes "through the looking-glass") to the corresponding square on the opposite board. (So, if a piece is moved on board A, it is transferred to board B at the completion of its move; if the piece started on board B, it ends up on board A.)

For example, after the opening moves 1. Nf3 e6, the white knight and black pawn transfer after moving on board A to their corresponding squares on board B. If the game continued 2. Ne5 Bc5, the knight returns to board A and the bishop finishes on board B. (See diagram.)
A move in Alice Chess has two basic stipulations: the move must be legal on the board on which it is played, and the square transferred to on the opposite board must be vacant. (Consequently, capture is possible only on the board a piece currently stands: pieces on board A can capture only pieces on board A; pieces on board B can capture only pieces on board B.) After capture, the capturing piece transfers to the opposite board the same as a non-capturing move.
To demonstrate, if the above game continued 3. Nxf7, the knight transfers to board B. Then with Black to move, both 3...Kxf7 and 3...Bxf2+ are not possible. Black cannot play 3...Qd4 either, since the queen may not hop over the pawn on d7. But the move 3... Bg1 is possible (see diagram), despite the fact a white pawn sits on f2 on board A. (The bishop move on board B is legal, and the square transferred to, g1 on board A, is vacant.)
A final stipulation applies specially to moves by the king: a king may not transfer to a vacant square on the opposite board, if this would put the king in check. Castling is largely regarded as permitted in Alice Chess. The en passant rule is normally not used, but can be.

Famous quotes containing the words move and/or rules:
“Increasingly in recent times we have come first to identify the remedy that is most agreeable, most convenient, most in accord with major pecuniary or political interest, the one that reflects our available faculty for action; then we move from the remedy so available or desired back to a cause to which that remedy is relevant.”
—John Kenneth Galbraith (b. 1908)
“Never invite to dinner: those who won’t decide until the last minute; those who come more than half an hour late; those who want to bring along two or three friends; drunks; monologists; those who stay until three o’clock in the morning; those who think that conversation means having an argument; those who take a high moral tone; those who are stupid, ugly, or dull. Enforcement of these rules will enable one to eat alone every night in comfort.”
—Mason Cooley (b. 1927)
