12. A piece abandoned is a completed move. [In all games this law should be observed, as nothing is so annoying to an opponent as to be asked to allow a move to be amended.]
13. A false or illegal move must be rectified, or the game resigned; such move may be allowed to remain, at the option of the adversary. [By a false move is meant the moving backward, or sideways, or on to the wrong-colour square.]
14. If a player in the act of taking remove one of his own men from the board, it cannot be replaced, except by consent of the opponent.
15. When three or more kings are opposed to a weaker force, the game must, when the opponent gives notice to count, be won within forty moves, or abandoned as drawn.
16. When two kings are opposed to one, the game is to be declared drawn, unless the player with the stronger force win in twenty moves. [From any part of the board two kings can win against one in fifteen or sixteen moves.]
17. Notice must be given of the intention to count the moves. [Twenty or forty, as the case may be; one for the combined move of both colours.]
18. When several pieces can be taken in one continuous move, no piece may be taken up off the board until the move is completed. The player failing to take all the men may be huffed. [As in [Rule 9].]
19. When a man arrives at a square in the last row on the opposite side of the board, he must be immediately crowned. But the king cannot move till the opposing player has made his move.
20. Kings can move backward or forward, one square at a time only; and, to take two or more pieces in one move, there must be a vacant square behind each individual piece.
21. Disputes are to be decided by an umpire, or a majority of the company.
