It seems to me that the meanings attributable to an IB are those meanings that would apply had the bid been sufficient. So given the auction 1♣-(1♠)-1♠, the relevant meanings are the meanings of 1♠ in the auctions 1♣-(P.)-1♠, 1♣-(1♦)-1♠, and 1♣-(1♥)-1♠. Possibly the auctions 1♣-(1♠)-2♠, 1♣-(1/2♦)-2♠, 1♣-(1/2♥)-2♠, 1♣-(1NT)-2♠, 1♣-(P.)-2♠, 1♣-(2♣)-2♠ should also be considered.

Thanks to offender’s comment, we know the insufficient bid was intended to show spades - no need for all that “attributable” stuff!

To allow opener to not be barred, responder will need to either:

1. Make the cheapest bid which shows spades
2. Make a comparable call (a call which shows 4-plus spades with more than a very weak hand - or with “similar meaning”)

Would 1NT be allowed to be comparable?

a. Hand strength is definitely more limited (about 7 to 11 HCP instead of 5-plus HCP).

b. Suit length for a 1NT bid would nearly always be 3-plus spades with some spade strength. This is not more defining than 4-plus spades. However, it is up to the Director to judge if this is similar enough to be allowed as a comparable call.

If the Director allows 1NT to be comparable, opener is not barred and the auction continues normally. Later, if the Director feels the extra information (four or five spades in responder’s hand instead of three spades) allowed offenders a good score, the score can be adjusted.

I agree that allowing the insufficient bidder to replace
1S with 1NT has let him show his partner that he has 4+
spades and unknown point count. While 1NT might only
show a spade stopper with limited strength. Doesn't seem
like 1NT is comparable and looks like it could be UI.

Also the offender could have made the 1NT bid just to avoid
partner being barred from bidding. More advanced players
certainly could have worked this out.

And how could the director know what the situation is
without looking at the offender's hand?

Incidentally I've seen situations where the director does
look at one of the player's hands before making a ruling.

A bid (any bid) is not UI because it is not I. It's a bid.

I would not allow 1NT to be considered comparable. But I can see the logic in it being “similar meaning”. If we are supposed to allow that much flexibility (as seen by those possible future examples we hope to see issued by the laws commissions soon), then I’ll adjust my personal standard of “similar meaning”.

Is it really necessary to bring this up in every discussion of UI and MI? The distinction between the I and the action that transmits the I is practically never significant, so it's not unreasonable to conflate them.

A bid is UI if it is a withdrawn bid by partner and partner has not yet made a comparable call (or cheapest bid showing same denominations for insufficient cases).

[blackshoe]

Le sigh. Put it bluntly, the difference is significant to me. If you don't think it matters, well, you're entitled to your opinion.

Bud: No. Same objection as in my original post.

Ed, not sure to what you are objecting. My contention of Laws 30B1(a) and Law 31B1 stating UI law applies to offender’s partner until offender makes his next (legal) call which the Director will judge to be comparable or not?

The only players who have information about 1-level responses on their CCs are those who play transfer responses, and they also should alert these bids.

Alerting doesn't help. If it starts 1♣ 1♦ 1♦, opener is not going to alert, so nobody may be aware they are playing transfer responses. Then when offender corrects to 2♦, which therefore after already having shown hearts, carries some additional information such as a diamond suit with four hearts, or an XYZ type GF, nobody other than opener knows. It seems wrong that the rule is assisting the passing of UI.

Surely in every instance of such corrections the director MUST check methods, even if the initial thought in this case may be to wave "play on".

No. What you said is "A bid is UI if…" You have, as Barry put it, conflated UI with an action (a bid) that may have conveyed UI. Barry thinks this doesn't matter. I think it does. Sloppy thinking begets bad rulings.

Yeah, Ed, I know you and I don't agree on this.

In my opinion, I think knowledge partner attempted to make a call (which was illegal and withdrawn) all by itself is UI even without knowledge of what the withdrawn call happened to be.

And knowing the specific call that was withdrawn is even more information about offender's hand that offender's partner is not entitled to possess.

He's not arguing against that. He's just saying that the withdrawn call transmitted UI, not that it is UI.

E.g. when someone is speaking, their words aren't information in themselves, they just transmit information.

[bixby]

The offender's comment "I didn't see the intervening bid" is UI, isn't it? Shouldn't the offender's partner be required to ignore information gained from that comment? I would think that someone who makes an insufficient bid should remain silent as to why it happened, except if asked by the Director away from the table, although spontaneous explanations of the kind given here are common in practice.

And once again, I wonder whether it is appropriate for even the Director to ask why the insufficent bid was made. Is the Director required to, or even permitted to, accept the offender's answer to that question? The "meaning" of the insufficient bid could vary greatly depending on why it happened (e.g., offender didn't see the intervening bid; offender saw the intervening bid and thought she was cue-bidding over it), so it is very important information, but it seems a little fishy to let the offender shape the ruling by giving the reason. What is the proper procedure?

[jerdonald]

There may be several reasons for an insufficient bid.
1) pulled the wrong card.
2) didn't see the intervening bid.
3) thought the intervening bid was a diamond not a heart.
4) Partners have an agreement on what an insufficient bid
would show, real UI and illegal but possible under this rule.
5) etc.

I would think most offenders would opt for number 1 no matter what
the real reason.

If the director can't ask the offender why they made it then he
has to assume he knows why. Seems like the director is not only
making a ruling but in a way is participating in the bidding.

I still think the way they enforced the old rule worked quite well
and am still trying to figure out why they made this change.

Yes. Yes. Yes. It is. Required, no; permitted, yes. I'll address proper procedure later.

[blackshoe]

When the director is called to the table (Law 9), his first job is to find out why he was called. After that, he needs to gather all pertinent facts. Once he has the pertinent facts, assuming they are agreed by both sides, he rules according to the law.

The procedure for rectifying an insufficient bid is as follows:

Was the insufficient bid was out of rotation?
...Yes: Law 31 applies
....No: Explain that offender's LHO may accept the IB, in which case the auction continues with no further rectification, and that otherwise LHO must substitute a legal call, some of which will allow the auction to continue without further rectification and some of which will require offender's partner to pass throughout the auction.
....Does offender's LHO accept the IB?
........Yes. Auction proceeds, no further rectification. Law 27A.
.........No. Explain that if offender substitutes the lowest sufficient bid that specifies the same denomination(s) as the IB the auction proceeds without further rectification (Law 27B1{a}); if he substitutes a comparable call (Law 23) the same (Law 27B1{b}). Otherwise if offender substitutes a sufficient bid or a pass his partner must pass for the remainder of the auction (Law 27B2); if he attempts to substitute a double or a redouble (unless 27B1{b} applies) that call is cancelled, offender must substitute a sufficient bid or a pass, and his partner must pass for the remainder of the auction (Law 27B3). If the offender attempts to substitute another insufficient bid go back to line 3 (...No, explain...) but if the new IB is not accepted Law 27B3 applies (offender must substitute a sufficient bid or a pass; his partner must pass for the remainder of the auction (Law 27B4).
............Apply the appropriate law according to the previous entry and offender's choice of replacement call. If Law 12B1 (either sub-part) was applied, then if the director determines after the play (this means he must look at it, even if no one asks him to do so) that without assistance gained from the infraction the NOS was damaged because the outcome might well have been different, he shall adjust the score.

What is a comparable call?

Quote

Law 23A. Definition
A call that replaces a withdrawn call is a comparable call, if it:
1. has the same or similar meaning as that attributable to the withdrawn call, or
2. defines a subset of the possible meanings attributable to the withdrawn call, or
3. has the same purpose (e.g. an asking bid or a relay) as that attributable to the withdrawn call.

So how does the director determine what meaning is attributable to the withdrawn call (in this case the IB)? He should take the offender away from the table and ask him what he was trying to do with the withdrawn call. The ACBL has produced some pretty decent videos on this.

[jerdonald]

Law 23A specifies some guidelines but in my post the bidding went
1D, 1S, 1S and the insufficient bidder was allowed to bid 1NT.

I don't see how 1NT is comparable with 1S unless you use the 23A.2 that
says "defines a subset of the possible meanings" which is about as open
ended and vague as it gets.

I still have the same question. What was wrong with, as I have always seen,
having the offender make the bid sufficient or passing?

That has not been the law in the 25 years or so I've been directing. So I'd have to ask where and when you've seen this, what would happen after offender makes the bid sufficient, and what would happen after he passes. If, as I suspect, after he makes it sufficient the auction proceeds without further rectification (the situation under the current laws)there's nothing wrong with that, but if, again as I suspect, after he passes, his partner is required to pass for the remainder of the auction (also the situation under the current laws) that's fine too as far as I'm concerned. But if those are the only two possibilities, well, the current law (and the previous one, and probably the one before that) is an attempt to get a "bridge result" at the table as often as possible, while still protecting the non-offending side. Prior versions of the law didn't do that very well, hence the change. Your version (make it sufficient or pass) hardly does it at all.

Yes, Law 23 is a bit complicated. That's why directors get paid the big bucks.

 barmar, on 2018-January-26, 09:44, said:

The old law wasn't as simple as you suggest.

They've simply replaced "same meaning as or a more precise meaning" with the "comparable call" criteria. Both require the TD to determine the meaning of the insufficient bid, and compare that with the replacement.

The old laws required the TD to determine the intended meaning of the insufficient bid, the new laws require them to consider "attributable meanings". These are not necessarily the same thing.

I don't think the director should allow such comments to restrict the set of meanings attributable to the insufficient bid. The TD should establish what meanings are attributable from the auction alone, and then tell the players the comments are UI to offender's partner, AI to the opponents.

I would imagine this could sometimes help the director establish which meanings are attributable to the insufficient bid, perhaps by revealing something about their agreements that might otherwise have been unclear, but I don't think the intended meaning should be given any more weight than other attributable meanings.
