IV. When a player undertakes to give check-mate with one of his Pawns, or with a particular Pawn, the said Pawn must not be converted into a piece.
V. When a player accepts the odds of two or more moves, he must not play any man beyond the fourth square, i.e., he must not cross the middle line of the board, before his adversary makes his first move. Such several moves are to be collectively considered as the first move of the player accepting the odds.
VI. In the odds of check-mating on a particular square it must be the square occupied by the King mated, not by the man giving the mate.
VII. The player who undertakes to win in a particular manner, and either draws the game, or wins in some other manner, must be adjudged to be the loser.
In all other respects, the play in games at odds must be governed by the regulations before laid down.
RULES FOR PLAYING CORRESPONDENCE AND CONSULTATION GAMES.
I. In playing a game by correspondence or in consultation, the two parties shall always agree beforehand in writing or otherwise as to the persons who are to take part in the contest, as to the time and mode of transmitting the moves, as to the penalties to be inflicted for any breach of the contract, and as to the umpire or referee.
II. In games of this description each party is bound by the move dispatched; and in this connection the word move refers to what is intelligibly written, or delivered viva voce.
In any game the announcement of a move which does not include the actual transfer of a man from one square to another, shall be considered as a move not intelligibly described within the meaning of this section.
III. Each party must be bound by the move communicated in writing, or by word of mouth, to the adversary whether or not it be made on the adversary’s board. If the move so communicated should prove to be different from that actually made on the party’s own board, the latter must be altered to accord with the former.
