If it is a defender's turn to play and that defender has two or more penalty cards that can legally be
played, declarer designates which is to be played at that turn.
Offender's Partner to Lead
When a defender has two or more penalty cards in one suit, and declarer requires the defender's partner to lead that suit,
the cards of that suit are no longer penalty cards and are picked up; the defender may make any legal play to the trick.
When a defender has two or more penalty cards in one suit, and declarer prohibits the defender's partner from leading that
suit, the defender picks up every penalty card in that suit and may make any legal
play to the trick. The prohibition continues until the player loses the lead.
When a defender has penalty cards in more than one suit [see Law 50D2(a)] and his partner is to lead,
declarer may require the defender's partner to lead a specified suit in which the defender has a penalty card [but
B1(a) preceding then applies].
When a defender has penalty cards in more than one suit and his partner is to lead, declarer may prohibit the defender's
partner from leading one or more of such suits; the defender then picks up every penalty card in every suit prohibited by
declarer and makes any legal play to the trick. The prohibition continues until the player loses the lead.
When a defender has penalty cards in more than one suit and his partner is to lead, declarer may elect not to require or
prohibit a lead, in which case the defender's partner may lead any card and the penalty
cards remain on the table as penalty cards. If this option is selected Laws 50 and 51
continue to apply for as long as the penalty cards remain.
