+p.boxed
+ | If a piece is checkmated (as if it was a king), it is captured.
+
+p.
+ 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.
+ Pieces cannot be taken in the normal way, only by the "mate-capture"
+ described above.
+
+p The game ends when a king is "mate-captured".

+p.
+ Note about moves notation: since captures do not occur on final squares,
+ an "X" mark is appended to the move to indicate a capture.
+ To keep notation short the potential list of captured squares is not written.
+
+h3 "Suicide" note
+
+p.
+ 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.
