2 | If a piece is attacked and cannot move out of attack, it is captured.
5 Any piece that is attacked, but which cannot escape capture by moving away,
6 capturing the attacking piece, or interposing the attacking piece is
7 considered to be mated, and is removed from the board.
8 Note that such a move does not need to be played: if a piece is attacked
9 but not mated, it is not removed.
10 Thus, kings and other pieces may remain under check.
13 Pieces cannot be taken in the normal way, only by the "mate-capture"
16 p The game ends when a king is "mate-captured".

24 Note about moves notation: since captures do not occur on final squares,
25 an "X" mark is appended to the move to indicate a capture.
26 To keep notation short the potential list of captured squares is not written.
31 In the current implementation, all pieces except kings can "commit suicide",
32 that is to say move or be left on a square where they are mated.
