5 | Queens, rooks, bishops and knights begin the game in a reserve below | |
6 | the board, because their location isn't determined yet. | |
7 | At each turn, you can either move something already defined on the board, or | |
8 | ol | |
9 | li move a piece from your reserve to any question mark, and then | |
10 | li move the now defined piece on the board. | |
11 | ||
12 | p An undefined piece gives check if some specialization giving check exists. | |

22 | At the first turn, you must select a square for the king anywhere on | |
23 | first rank. This deviates from the original intention of the author, | |
24 | because castling rules would be rather tedious to implement. | |
25 | Thus, you can instead "castle on move 1" :-) | |

28 | If one of your undefined pieces is captured, you first have to choose which | |
29 | one was captured from the reserve: place it at the capture location. | |

32 | If after your move all your pieces are defined (and weren't before), then | |
33 | all pieces on board revert to undefined state, unless: | |
34 | ul | |
35 | li. | |
36 | all your pieces (board + reserve) are now of the same type, | |
37 | in which case none is put back in reserve, or | |
38 | li. | |
39 | all opponent's pieces are of the same type, in which case | |
40 | they also remain defined. | |
