, such cards are exposed and are liable
to be called; but if either adversary retain his hand he cannot be
forced to abandon it. Cards exposed by the declarer are not liable to
be called. If the declarer say, "I have the rest," or any other words
indicating that the remaining tricks or any number thereof are his, he
may be required to place his cards face upward on the table. His
adversaries are not liable to have any of their cards called should
they thereupon expose them.

73. If a player who has rendered himself liable to have the highest or
lowest of a suit called (Laws 80, 86 and 92) fail to play as directed,
or if, when called on to lead one suit he lead another, having in his
hand one or more cards of the suit demanded (Laws 76 and 93), or if,
called upon to win or lose a trick, fail to do so when he can (Laws 71,
80 and 92), or if, when called upon not to play a suit, fail to play as
directed (Laws 65 and 66), he is liable to the penalty for revoke,
unless such play be corrected before the trick is turned and quitted.

74. A player cannot be compelled to play a card which would oblige him
to revoke.

75. The call of an exposed card may be repeated until such card has
been played.

LEADS OUT OF TURN

76. If either of the declarer's adversaries lead out of turn the
declarer may either treat the card so led as an exposed card or may
call a suit as soon as it is the turn of either adversary to lead.

77. If the declarer lead out of turn, either from his own hand or from
dummy, he incurs no penalty; but he may not rectify the error after the
second hand has played.

78. If any player lead out of turn and the three others follow, the
trick is complete and the error cannot be rectified; but if only the
second, or second and third play to the false lead, their cards may be
taken back; there is no penalty against any except the original
offender, who, if he be one of the declarer's adversaries, may be
penalized as provided in Law 76.

79. If a player called on to lead a suit has none of it, the penalty is
paid.

CARDS PLAYED IN ERROR

80. Should the fourth hand, not being dummy or declarer, play before
the second, the latter may be called upon to play his highest or lowest
card of the suit played, or to win or lose the trick.

81. If any one, not being dummy, omit playing to a trick and such error
is not corrected until he has played to the next, the adversaries or
either of them may claim a new deal;
