partner has led
or played to the following trick.

86. If a player correct his mistake in time to save a revoke, any
player or players who have followed him may withdraw their cards and
substitute others, and the cards so withdrawn are not exposed. If the
player in fault is one of the declarer's adversaries, the card played
in error is exposed and the declarer may call it whenever he pleases;
or he may require the offender to play his highest or lowest card of
the suit to the trick, but this penalty cannot be exacted from the
declarer.

87. At the end of a hand the claimants of a revoke may search all the
tricks. If the cards have been mixed the claim may be urged and proved
if possible; but no proof is necessary and the claim is established if,
after it has been made, the accused player or his partner mix the cards
before they have been sufficiently examined by the adversaries.

88. A revoke must be claimed before the cards have been cut for the
following deal.

89. Should both sides revoke, the only score permitted shall be for
honors in trumps or chicane. If one side revoke more than once, the
penalty of 100 points for each extra revoke shall then be scored by the
other side.

91. Any player during the play of a trick or after the four cards are
played, and before they are touched for the purpose of gathering them
together, may demand that the cards be placed before their respective

92. If either of the declarer's adversaries, prior to his partner
playing, call attention to the trick, either by saying it is his, or
without being requested so to do, by naming his card or drawing it
towards him, the declarer may require such partner to play his highest
or lowest card of the suit led, or to win or lose the trick.

93. Either of the declarer's adversaries may call his partner's
attention to the fact that he is about to play or lead out of turn; but
if, during the play of a hand, he make any unauthorized reference to
any incident of the play, or of any bid previously made, the declarer
may call a suit from the adversary whose turn it is next to lead.

94. In all cases where a penalty has been incurred the offender is
bound to give reasonable time for the decision of his adversaries.
