| 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). |

| 41 | | As in the orthodox game, win by checkmating the king. It shouldn't be able to |
| 42 | | escape the check, not even by moving to the other 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. |
