| 3 | There are two boards. All pieces start on board 1. |

| 6 | Two boards are used in this variant (represented on only one). |
| 7 | Upside-down pieces appear at every "normal" pieces moves: they live on |
| 8 | another board. When moved, they return to the initial board. |
| 9 | Orthodox rules apply on each board. |
| 10 | In addition, the final square should not be occupied by a piece from the |
| 11 | other board (thus allowing to represent all on one board). |

| 28 | En-passant and castle occur as they do in the standard game. |
| 29 | More specifically, en-passant is possible regardless of the worlds pawns |
| 30 | are in. This is justified because pawns "go through the mirror" while moving, |
| 31 | and can thus be captured either right after or just before they pass the |
| 32 | mirror. |
| 33 | Castling should be legal according to orthodox rules on the board 1 (it |
| 34 | cannot occur on board 2, because it would mean king and rook moved). |
| 35 | Moreover, the king cannot be in check on board 2 after castling. |

| 40 | As in the orthodox game, win by checkmating the king. |
