| 2 | | If a piece is checkmated (as if it was a king), it is captured. |
| 3 | |
| 4 | p. |
| 5 | If a piece is attacked and no orthodox move can prevent its (normal) capture, |
| 6 | it is considered to be mated and is removed from the board. |
| 7 | If such an orthodox move exists, it doesn't have to be played |
| 8 | (it could even be illegal because normal captures are forbidden): |
| 9 | the piece is not captured. |
| 10 | Thus, kings and other pieces may remain under check. |
| 11 | |
| 12 | p. |
| 13 | If after a mate-capture another is made possible thanks to some pieces |
| 14 | removal, then the new mate-capture is applied and the process goes on. |

| 37 | Note about moves notation: since captures do not occur on final squares, |
| 38 | an "X" mark is appended to the move to indicate a capture. |
| 39 | To keep notation short the list of captured squares is not written. |

| 42 | |
| 43 | p. |
| 44 | In the current implementation, all pieces except kings can "commit suicide", |
| 45 | that is to say move or be left on a square where they are mated. |
