II. Any card dropped with its face upwards, or in any way exposed on or
above the table, even though snatched up so quickly that no one can
name it.
74. If either of the dealer's adversaries play to an imperfect trick the
best card on the table, or lead one which is a winning card as against the
dealer and his partner, and then lead again, without waiting for his
partner to play, or play several such winning cards, one after the other,
without waiting for his partner to play, the latter may be called on to
win, if he can, the first or any other of those tricks, and the other cards
thus improperly played are exposed cards.
75. Should the dealer indicate that all or any of the remaining tricks are
his, he may be required to place his cards face upwards on the table; but
they are not liable to be called.
76. If either of the dealer's adversaries throws his cards on the table
face upwards, such cards are exposed, and liable to be called by the
dealer.
77. If all the players throw their cards on the table face upwards, the
hands are abandoned, and the score must be left as claimed and admitted.
The hands may be examined for the purpose of establishing a revoke, but for
no other purpose. {241}
78. A card detached from the rest of the hand of either of the dealer's
adversaries, so as to be named, is liable to be called; but should the
dealer name a wrong card, he is liable to have a suit called when first he
or his partner have the lead.
79. If a player, who has rendered himself liable to have the highest or
lowest of a suit called, or to win or not to win a trick, fail to play as
desired, though able to do so, or if 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.
80. If either of the dealer's adversaries lead out of turn, the dealer may
call a suit from him or his partner when it is next the turn of either of
them to lead, or may call the card erroneously led.
81. If the dealer 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.
82. If any player lead out of turn, and the other three have followed him,
the trick is complete, and the error cannot be rectified; but if only the
second, or the second and third, have played to the false lead, their
cards, on discovery of the mistake, are taken back; and there is no penalty
against any one, excepting the original offender, and then only when he is
one of the dealer's adversaries.
83. In no case can a player be compelled to play a card which would oblige
him to revoke.
