| 11 | At the very first move, players may decide to swap positions of adjacent |
| 12 | knights and bishops. Either on both sides, or on one only. To bypass this |
| 13 | step (or end it after a first swap), move your king to the opponent's king. |

| 20 | p. |
| 21 | Known pieces move as usual, with one exception: the pawn only promotes |
| 22 | to a queen (named "Gilding" in this game). Additionally, all pieces can |
| 23 | promote — except queen and king: |
| 24 | ul |
| 25 | li Rook promotes into Dragon = Rook + King. |
| 26 | li Knight promotes into Scepter = Knight + King. |
| 27 | li Bishop promotes into Horse = Bishop + King. |
| 28 | li Cardinal promotes into Queen (called "Whole" here). |
| 29 | li Marshal promotes into Queen (called "Apricot" here). |
| 30 | p. |
| 31 | All these promotions are optional. They are available after a move ending |
| 32 | at or starting from the last two ranks. |
| 33 | |
| 34 | p. |
| 35 | Each captured piece is first returned to its unpromoted version (if |
| 36 | applicable), and then added to a reserve. It can be dropped later |
| 37 | in place of a move. |

| 40 | |
| 41 | p. |
| 42 | Pawns can initially advance three squares. |
| 43 | On the third rank, they can still advance two squares. |
| 44 | A dropped pawn cannot give checkmate. |
| 45 | |
| 46 | p While castling, the king moves three squares lateraly. |
| 47 | |
| 48 | p. |
| 49 | Threefold repetition is a draw, unless caused by a perpetual check. |
| 50 | In this case, the player giving check loses. |
