SECTION TWO
IRREGULARITIES IN PROCEDURE

LAW 46 - INCOMPLETE OR ERRONEOUS CALL OF CARD FROM DUMMY 

A. Proper Form for Designating Dummy's Card

When calling a card to be played from dummy, declarer should clearly state both the suit and the rank of the desired card.

B. Incomplete or Erroneous Call

In case of an incomplete or erroneous call by declarer of the card to be played from dummy, the following restrictions apply (except when declarer's different intention is incontrovertible):

1. Incomplete Designation of Rank

If declarer, in playing from dummy, calls "high", or words of like import, he is deemed to have called the highest card; in fourth seat he may be deemed to have called for the lowest winning card of the suit indicated; if he directs dummy to win the trick, he is deemed to have called the lowest winning card; if he calls "low", or words of like import, he is deemed to have called the lowest.

2. Designates Suit but Not Rank

If declarer designates a suit but not a rank, he is deemed to have called the lowest card of the suit indicated.

3. Designates Rank but Not Suit

If declarer designates a rank but not a suit:

(a) In Leading

Declarer is deemed to have continued the suit in which dummy won the preceding trick, provided there is a card of the designated rank in that suit.

(b) All Other Cases

In all other cases, declarer must play a card from dummy of the designated rank if he can legally do so; but if there are two or more such cards that can be legally played, declarer must designate which is intended.

4. Designates Card Not in Dummy

If declarer calls a card that is not in dummy, the call is void and declarer may designate any legal card.

5. No Suit or Rank Designated

If declarer indicates a play without designating either a suit or rank (as by saying, "play anything", or words of like import), either defender may designate the play from dummy.
