75.—The penalty for a revoke—
I. Is at the option of the adversaries, who, at the end of the hand, may either take three tricks from the revoking player, and add them to their own tricks, or deduct three points from his score, or add three to their own score (the adversaries may consult as to which penalty they will exact);
II. Can be claimed for as many revokes as occur during the hand, and a different penalty may be exacted for each revoke;
III. Is applicable only to the score of the game in which it occurs;
IV. Cannot be divided, i.e. a player cannot add one or two to his own score, and deduct one or two from the revoking player;
V. Takes precedence of every other score—e.g., The claimants two—their opponents nothing—the former add three to their score—and thereby win a treble game, even should the latter have made thirteen tricks, and held four honours.
76.—If a player who has become liable to have the highest or lowest of a suit called, or to win or not to win a trick (when able to do so), fail to play as desired, or if a player, when called on to lead one suit, lead another, having in his hand one or more cards of that suit demanded, he incurs the penalty of a revoke.
77.—A revoke is established, if the trick in which it occur be turned and quitted, i.e., the hand removed from that trick after it has been turned face downwards on the table—or if either the revoking player or his partner, whether in his right turn or otherwise, lead or play to the following trick. Throwing down the hand, or claiming game, constitute acts of play within the meaning of leading or playing to the following trick.
78.—A player may ask his partner whether he has not a card of the suit which he has renounced, or whether he has played as desired or demanded; should the question be asked before the trick is turned and quitted, subsequent turning and quitting by the adversaries does not establish the revoke, and the error may be corrected, unless the question be answered in the negative, or unless the revoking player or his partner have led or played to the
following trick; but if the revoking player or his partner has turned the trick before the question is answered, the revoke is established.
79.—At the end of a hand, the claimants of a revoke may search all the tricks.[[62]]
80.—If a player discover his error in time to save a revoke, the adversaries, whenever they think fit, may call the card thus played in error, or may require him to play his highest or lowest card to that trick in which he has renounced;—any player or players who have played after him may withdraw their cards and substitute others; the cards withdrawn are not liable to be called.
