f To correct an erroneous score.
61. Should the declarer's partner call attention to any other incident of the play in consequence of which any penalty might have been exacted, the declarer is precluded from exacting such penalty.
62. If the declarer's partner, by touching a card or otherwise, suggest the play of a card from dummy, either adversary may call upon the declarer to play or not play the card suggested.
63. Dummy is not liable to the penalty for a revoke; if he revoke and the error be not discovered until the trick is turned and quitted, whether by the rightful winners or not, the trick must stand.
64. A card from the declarer's own hand is not played until actually quitted; but should he name or touch a card in the dummy, such card is considered as played unless he, in touching the card, say, "I arrange," or words to that effect. If he simultaneously touch two or more such cards, he may elect which one to play.
CARDS EXPOSED BEFORE PLAY
65. If, after the cards have been dealt, and before the trump declaration has been finally determined, any player lead or expose a card, the partner of the offending player may not make any further bid or double during that hand, and the card is subject to call. When the partner of the offending player is the original leader, the declarer may prohibit the suit of the exposed card being the initial lead.
66. If, after the final declaration has been made and before a card is led, the partner of the leader to the first trick expose a card, the declarer may, in addition to calling the card, prohibit the lead of the suit of the exposed card; should the rightful leader expose a card it is subject to call.
CARDS EXPOSED DURING PLAY
67. All cards exposed after the original lead by the declarer's adversaries are liable to be called, and such cards must be left face upward on the table.
