- | If a piece is attacked and cannot move out of attack, it is captured.
+ | If a piece is checkmated (as if it was a king), it is captured.
p.
- Any piece that is attacked, but which cannot escape capture by moving away,
- capturing the attacking piece, or interposing the attacking piece is
- considered to be mated, and is removed from the board.
- Note that such a move does not need to be played: if a piece is attacked
- but not mated, it is not removed.
+ If a piece is attacked and no orthodox move can prevent its (normal) capture,
+ it is considered to be mated and is removed from the board.
+ If such an orthodox move exists, it doesn't have to be played
+ (it could even be illegal because normal captures are forbidden):
+ the piece is not captured.
Thus, kings and other pieces may remain under check.
+p.
+ If after a mate-capture another is made possible thanks to some pieces
+ removal, then the new mate-capture is applied and the process goes on.

Note about moves notation: since captures do not occur on final squares,
an "X" mark is appended to the move to indicate a capture.

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