LAWS OF CHESS.
1778. The rules given below are based upon the code published in "Walker's Art of Chess Play." The word piece frequently includes the pawn.
1779. If the board or pieces be improperly placed, or are deficient in number (except in the case of odds), the game must be recommenced, if the error is discovered before the fourth move on each side (the eighth move of the game.) If not discovered before this stage, the game must proceed.
1780. If the player gives odds, and yet omits to remove the odds from the board at the commencement, he may recommence the game, and remove the odds given, provided he discover his error before playing his fourth move.
