60.—If any one play to an imperfect trick the winning card on the table, and then lead without waiting for his partner to play, or lead one which is a winning card as against his adversaries, 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 subsequent cards thus improperly played are exposed cards.
61.—If a player or players (not being all) throw his or their cards on the table face upwards, such cards are exposed, and liable to be called, each player's by the adversary; but no player who retains his hand can be forced to abandon it.
62.—If all four players throw their cards on the table face upwards, the hands are abandoned; and no one can again take up his cards. Should this general exhibition show that the game might have been saved or won by the losers, neither claim can be entertained unless a revoke be established. The revoking players are then liable to the following penalties: they cannot under any circumstances win the game by the result of that hand, and the adversaries may add three to their score, or deduct three from that of the revoking players, for each revoke.
63.—If a card be detached from the rest of the hand, which an adversary at once correctly names, such card becomes an exposed card; but should the adversary name a wrong card, he is liable to have a suit called when he or his partner next have the lead.
64.—If any player lead out of turn, his adversaries may either call the card erroneously led, or may call a suit from him or his partner when it is next the turn of either of them to lead. The penalty of calling a suit must be exacted from whichever of them next first obtains the lead. It follows that if the player who leads out of turn is the partner of the person who ought to have led, and a suit is called, it must be called at once from the right leader. If
he is allowed to play as he pleases, the only penalty that remains is to call the card erroneously led. The fact that the card erroneously led has been played without having been called, does not deprive the adversaries of their right to call a suit. If a suit is called, the card erroneously led may be replaced in the owner's hand.
65.—If it is one player's lead, and he and his partner lead simultaneously, the penalty of calling the highest or lowest card of the suit properly led may be exacted from the player in error, or the card simultaneously led may be treated as a card liable to be called.
66.—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; there is no penalty against any one, excepting the original offender, whose card may be called—or he, or his partner (whichever of them next first has the lead), may be compelled to play any suit demanded by the adversaries.
67.—In no case can a player be compelled to play a card which would oblige him to revoke.
