| 2 | | No captures. Pieces under attack insufficiently defended change color. | |

| 5 | Conversion occurs when the amount of persuasion exceeds the | |
| 6 | amount of support. Pieces persuade and support according to | |
| 7 | their standard attack moves. Opposing pieces persuade, friendly support. | |

| 10 | For example on the following diagram, 1.Nf5 attacks g7. | |
| 11 | Since the bishop is undefended, it turns white. Same for the pawn e7. | |
| 12 | Then, the rook f8 is converted. This allows to convert both the knight | |
| 13 | on d8 and the bishop on g8. Finally, the pawns f7 and h7 are under attack | |
| 14 | and thus also change color. | |

| 4fcb0c04 | 24 | The game ends when a king is converted, and no king can be converted |
| a930dd71 BA |
25 | at the next turn. Note that kings may be exchanged, as on the following |
| 26 | diagram: 1...g6 would convert back the original black king on e7, but | |
| 4fcb0c04 | 27 | 1...Nb6 is also possible, turning the white king on a4 into black. |

| 50 | It is possible for pieces to persuade or support through other | |
| 51 | friendly pieces. For example, rooks and queens in the same orthogonal | |
| 52 | or bishops and queens in the same diagonal. | |
| 53 | li. | |
| 4fcb0c04 | 54 | The pawn is forbidden to move through a cell which is overly persuaded |
| a930dd71 BA |
55 | during its initial two-step move. |
| 56 | li. | |
| 4fcb0c04 | 57 | A king is allowed to move to cells which are being persuaded as |
| a930dd71 BA |
58 | long as the level of persuasion is not greater than its support. |
