| 7 | | His website | |
| 8 | | contains many examples and explanations. | |

| 21 | Queens, rooks, bishops and knights begin the game in a reserve below | |
| 22 | the board, because their location isn't determined yet. | |
| 23 | At each turn, you can either move something already defined on the board, or | |
| 24 | ol | |
| 25 | li move a piece from your reserve to any question mark, and then | |
| 26 | li move the now defined piece on the board. | |
| 27 | ||
| 28 | p An undefined piece gives check if some specialization giving check exists. | |

| 38 | At the first move, you must select a square for the king anywhere on | |
| 39 | the first rank — preferably in a corner. This deviates from the | |
| 40 | original intention of the author, but this way you will not need to castle | |
| 41 | later in the game. Click on a square to place the king. | |

| 44 | If after your move all your pieces are defined (and weren't before), then | |
| 45 | all pieces on board revert to undefined state, unless: | |
| 46 | ul | |
| 47 | li. | |
| 48 | all your pieces (board + reserve) are now of the same type, | |
| 49 | in which case none is put back in reserve, or | |
| 50 | li. | |
| 51 | all opponent's pieces are of the same type, in which case | |
| 52 | they also remain defined. | |

| 64 | one was captured from the reserve: place it at the capture location. |
