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"

22 Note about moves notation: since captures do not occur on final squares,
23 an "X" mark is appended to the move to indicate a capture.
24 To keep notation short the potential list of captured squares is not written.
28 p The game ends when a king is "mate-captured".
