As usual the current law...
- ... Relies too much on the director's subjective judgement. Players naturally question the fairness of an adverse ruling when other players get favourable rulings in identical circumstances. It may seem to them that the ruling depends on how much the declarer trusts the player. The law puts directors in an impossible position when a ruling involves somebody they like or dislike. I bet such powers are not welcome to all directors
- ... Penalises those who abide by it (designating a card by rank and suit). But often
- ....Rewards and encourages those who break it (by touching a card or just naming its suit).
- ... Penalises players who tell directors the truth but
- ... Rewards and encourages plausible liars (and self-deluders).
- Declarer should specify dummy's card by rank and suit.
- If declarer says "J'adoube" then he may arrange dummy's cards. Otherwise a touched card is deemed played.
- If declarer just names the rank then he should be asked to complete the designation unless there is only one card of that rank in dummy.
- If declarer just names the suit this should always mean the lowest card in the suit (no exceptions).
- If declarer says "run <suit>", this should mean play the entire suit from the top down.
- When declarer specifies a card (however sloppily), and that card is in dummy, then the director should not allow him to change it.
- Declarer should not even be allowed to change a designation in the same breath. For example, "king.. no knave of clubs" designates a king and "spade ... no heart" designates "lowest spade". (I think this last rule is fair and consistent, although some may regard it as draconian).
