18 | Two boards are used in this variant. Pieces from board 2 are represented on
19 | the main board, upside down.
20 | Any move played must be valid on the board it is played on.
21 | In addition, the final square should not be occupied by a piece from the other board
22 | (thus allowing to represent all on one board).

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