+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

+p.
+ 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.
