And yet the laws do require him to do so.
"Require" is too strong. 46A states:
When calling for a card to be played from dummy declarer
should clearly state both the suit and the rank of the desired card.
The introduction has: “should” do (failure to do it is an infraction jeopardising the infractor’s rights but not often penalised)
46B covers an incomplete or invalid designation, and gives some examples. Where a specification is similar to "high", "win" or "low", there is no problem. When a statement is similar to "anything" there is no problem. The lacuna was created by the lawmakers carelessly not saying what happens when declarer uses something that is not similar to "high", "win", "low" or "anything" and which does not name a rank or suit. Where the law is silent, the TD has to rule. The most draconian is to say that "and again" is similar to "play anything" but that does not seem correct. The most favourable to declarer (normally) is that "and again" means an adjacent card in the same suit. I think that to say that "and again" means the same card that dummy has just played in the quitted trick, and therefore declarer can play any card, makes no sense and rewards declarer for a breach of proper procedure. I don't know what the correct answer is in such situations.
I prefer to give the lawmakers credit for stating things for a reason - barmar
