-p.boxed.
- Every move played ends up on another board (the "other side of the mirror").
- There are two boards. All pieces start on board 1.
-
-p.
- Two boards are used in this variant (represented on only one).
- Upside-down pieces appear at every "normal" pieces moves: they live on
- another board. When moved, they return to the initial board.
- Orthodox rules apply on each board.
- In addition, the final square should not be occupied by a piece from the
- other board (thus allowing to represent all on one board).
-
-p Notation for Alice pieces was chosen as follow:
-ul
- li Pawn : S
- li Rook : U
- li Knight : O
- li Bishop : C
- li Queen : T
- li King : L

- En-passant and castle occur as they do in the standard game.
- More specifically, en-passant is possible regardless of the worlds pawns
- are in. This is justified because pawns "go through the mirror" while moving,
- and can thus be captured either right after or just before they pass the
- mirror.
- Castling should be legal according to orthodox rules on the board 1 (it
- cannot occur on board 2, because it would mean king and rook moved).
- Moreover, the king cannot be in check on board 2 after castling.

-p.
- As in the orthodox game, win by checkmating the king.
- It shouldn't be able to escape the check, not even by moving to the other
- board.
