Nightmare at the club

No real directing this month, except for a “guest” appearance at the club — I managed to call the moves to time, and sort out the scoring problems. Instead I tried playing the game yesterday but that was a disaster, the only thing I did right was to give a ruling on a board the real TD had not yet played.

All dummy's cards not displayed

The ruling concerned the problem of what to do when dummy manages to hide one of their cards when displaying their hand in dummy. Inevitably this does not get discovered until half way through the play, when the card above the hidden card is played. Dummy is at fault (Law 41D requires dummy spreads his hand in front of him on the table, face up ) but there is no prescribed penalty. We have to fall back on something (Law 12A1 will do) when the defenders have been damaged, and adjust to the result that would have happened if the defenders had been able to see all dummy's cards from the outset.

This sort of ruling comes up from time to time and appears on the internet: it is now covered in the EBU County Directors' course. Perhaps it should be covered explicity in the laws. It only needs another sentence in Law 41D.

If dummy fails to display his hand as specified, and the defenders are damaged, the director shall award an adjusted score.

Confession is good for the soul

The low point of the evening was a misinformation case.

WNES
1♣
(1♦)1♥ 2♦A
3♥ 4NT
5♦ Q5♥
End

East asked about 5♦ during the auction and South said “one ace or the king of trumps”.

The end of the round was called as play started. The opening lead was a diamond, won by East's queen, and then he cashed a top spade, but when he tried to cash ♦A it was ruffed by declarer. Declarer now crossed to dummy in spades and discarded a club on dummy's ♦K. This all seemed odd to South, as the only key card North could have was ♣A. South concluded that North did not have any key cards and then remembered they played RKCB 41/30. South told the table that he had given a misexplanation of 5♦ * but play continued. Declarer was able to complete a cross-ruff, finally drawing trumps in hand (when they broke 2–2) and cashing his established spade; making 5♥.

South again said there had been a misexplanation and the defence would have cashed the first three tricks if they knew declarer had no aces. But East/West were not interested and just wanted to move for the next round. Perhaps it would have been better if North had given up when the misexplanation came to light and claimed down –1 that would have happened if the defence had cashed their three tricks.

* Should he do so now? Law 20F4 says he should; Law 43A1a suggests otherwise.

Things we know that we know

Answers to Known Unknowns

This post is in reponse to Paul's request that I lift some of the fear, uncertainty and doubt in the previous post, and give some guidance on how best to handle the known difficulties detailed in that post. I will also take the liberty of describing how the laws might be changed.

Insufficient bids — what can LHO know?

I rule on the basis that LHO is allowed to know as much about the options available to the insufficient bidder that does not reveal what the insufficient bid was intended to mean nor what is in the insufficient bidder's hand. So LHO is allowed to know whether there is a Law 27B1a correction because the TD can usually determine if the insufficient bid is incontrovertibly not artificial and can determine if the lowest sufficient bid in the same denomination is (incontrovertibly) not artificial by reference to the offending side's system. But LHO is not allowed to know whether there are Law 27B1b corrections (rectification calls), nor what they are, just that there may be (other) calls that do not silence offender's partner.

This is consistent with what I did under the previous laws, and although it sometimes put a non-offending player in a difficult position, it is an approach that can be operated consistently.

How do we adjust for two non-offending sides in Law 86D?

The only approach I can recommend is AVE+ to both sides: I do not have to do anything else because Law 86D talks about the non-offending side.

The alternative approach of giving an assigned score for both sides, and so giving one non-offending side less than AVE+, is not explicitly required by the laws; and is not one that I can justify to the side who would get the bad score.

When declarer becomes dummy is dummy still dummy?

I would rule that dummy is not dummy when the opening lead is out of turn, until the options in Law 54 have been exercised. I would not rule that either player of the declaring side was in error in drawing attention to an irregularity when there is an opening lead out of turn, until dummy has been spread.

What does Law 21B2 mean for the players?

Obviously, there is no need to make a great deal of this: the outcomes is likely to be the same. The only real approach is to read the law as written, explain to the players that they can use the information from the withdrawn call; but there may be an adjustment at the end of the hand. In many circumstances, it may be more practical to tell the players nothing or to tell the players to treat the withdrawn call as unauthorised information (because that is what the TD will have to do later)!

The real answers - what the laws should say

Insufficient bids

There are a number of workable solutions to the insufficient bid law.

  • Offender's partner is silenced, whatever the correction;
  • Offender's partner is not silenced, whatever the correction;
  • Offender's partner is not silenced if the correction is the lowest sufficient bid in the same denomination, regardless of the meaning of the insufficient bid or the correction;
  • In any case, the insufficient bid is unauthorised information and there can be lead penalties;
  • If offender's partner is silenced, Law 23 applies;
  • The insufficient bid can still be accepted.

Two non-offending sides in Law 86D

In Law 86D, give any non-offending side the better of an assigned score from a favourable result and AVE+, and give any non-offending side the worse of an assigned score from an unfavourable result and AVE-.

When dummy is dummy

Dummy becomes dummy (is subject to the limitations in Law 43) when his hand is spread. If declarer starts to expose his hand after an opening lead out of turn, declarer becomes dummy and presumed dummy is not subject to the limitations in Law 43.

What does Law 21B2 mean?

I do not know what historical reasons have created Law 21B2 in its current form, but it should be changed so that Law 16D applies to the misinforming side's changed call. The withdrawn call is unauthorised information during the auction and play.
