EDIT: Played around with some numbers in Bridge Baron, and it suggests that the percentage of holding 22-24 when partner has at leatt is on the order of 0.03%.

[nige1's partner may well have written the SBU regulation, "responder is expected to bid whenever game is possible opposite a maximum", which is stronger in its meaning and would presumably lead to an illegal convention penalty in such a case]

Does the restriction you quote apply to Level 4 or just to Level 3? [edit] I've now checked this and it does seem to apply to Level 4 as well as Level 3. So, the final question is what their agreement was as to their Multi? What sort of hands were contained in it?

Anyway, agree with Paul. This hand certainly makes game opposite a strong variant so case closed.

I think that opposite a 22-24 NT game has a better than decent chance of making.
Having said that, I think that this regulation should be taken out immediately for the following reasons:
- It asks of responder to stop playing bridge. In this case, responder can see that if he has this hand 10 times, Pass will be right 10 times. And that is not because of a tactical joke on the opponents. It is because 2♦ has, by far, the best probability of being the right contract.
- It uses vague terminology, like "Responder is expected to explore game possibilities". That means something like: "Responder will explore game possibilities, but there are exceptions". Well, this hand with a void in hearts and a six card diamond suit would qualify as an exception.
- Because of the vague terminology, it misleads the opponents. They feel certain that they will get another turn to bid (after all, "responder is expected to"), and they will build their defense on that, but then it turns out that there is no such certainty, since "to expect" implies that exceptions are allowed and do occur. My son expects to get a bike for Christmas. I think he knows that it still depends on what Santa thinks of him.

Quote
11 G 10 General
Two of a Suit openings may be played as any one or two of the following:
(a) Strong: Any combination of meanings provided that it promises a minimum strength of ‘Extended Rule of 25’ (see 10 B 4).
(B.) Any combination of meanings which either:
(1) includes one specified suit of at least four cards; or
(2) has a specification which does not include holding at least four cards in the suit bid, and does not include two-suiters where the suit bid is the longer suit.
Notes:
(i) Responder is expected to explore game possibilities if his hand justifies it opposite the stronger types of his partner’s opening bid.
So a weak-only multi is permitted (11G10.b. (2)), except you should not call it a multi, as is passing it if your hand justifies it.

I agree but the accepted phrase is "Weak only multi" which I think conveys it quite well.

First there is a regulation which says:

Please note that the question does not reflect the wording of the regulation - not even close.
Second, Trinidad says:

But none of the reasons have anything to do with why the regulation exists! Surely, if you think a regulation is wrong, it should be because one of the following:
- it does not do what it is designed to do, or
- what it is designed to do is unnecessary

That's not true. Those are good reasons to think a regulation is wrong, but there are several others that are just as good:
- It creates a new problem (or combination of problems) worse than the problem(s) it solves.
- It's unenforceable, or at least unenforceable fairly.
- It was not created through due process.
Btw, his reason that the regulation uses vague terminology is exactly the same as your "it does not do what it is designed to do", so your criticism was not only wrong (imo), but also unfair.

I understand the intent of the regulation is to catch players who are misdescribing their multi-way bids: describing stronger options than they do not in fact actually open with the multi-way bid. The extreme example being players who play a weak-only multi but include a strong option in their description, in fact finding other opening bids with (say) 20-21 balanced or strong 4441 hands. This is particularly an issue at level 3 where a weak-only multi is not a permitted agreement.
Does passing a multi with no hearts and six diamonds give evidence that the stronger options are an illusion? No. It is evidence that the player understands conditional probability: whatever the a priori odds on the various options in the multi were, once you hold this shape and these high card points the odds have skewed greatly towards a weak hand and a weak hand with hearts. A player should be able to back those odds and the regulations should not prevent him from "playing bridge".

Robin, as always, covers the subject well and if the regulation said,
"Responder is expected to explore game possibilities if his hand justifies it."
then I'm sure nige1 and everyone would be happy with his explanation.
Unfortunately, the playing public is playing to the regulation that says
"Responder is expected to explore game possibilities if his hand justifies it opposite the stronger types of his partner’s opening bid."
There is no mention of 'intent', likelihood of holding a strong hand or 'playing bridge' that presumably the L&EC and TDs are working to. The regulation at Level 4 appears to be redundant, except to those foolish enough to believe that it means what it says.
(I think the Scottish regulation is just as foolish, btw)

Yeah, but the same is also true if you play multi as "weak 2 in a major, or a 3=4=5=1 hand with 26 hcp and a stiff Q of clubs". My impression is that the regulation intends to make such an agreement (which is basically equivalent to playing a weak-only multi) illegal.

I had always interpreted this regulation as meaning that responder can not bid game directly and, instead, must use a game invitational sequence.

There is a separate statement in the regulations (OB 11G6 bullet (v)) that one strong option must have a "reasonable frequency".
For the thread as a whole, it may also be relevant to quote OB 11G6 bullet (vi)

A. "Responder is expected to explore game possibilities if his hand justifies it."
and
B. "Responder is expected to explore game possibilities if his hand justifies it opposite the stronger options of opener’s Multi 2♦."
If the regulation is A, then responder is entitled to consider the probability of partner having the string option. When the regulation is B, that suggests to me that responder has to act if he'd want to be in game when partner is strong.
I agree that this is not really playing bridge, but the time to worry about that was when creating the regulation not when applying it.
I'm not convinced that the the intent of the regulation is solely to catch players who are misdescribing their multi-way bids. It's more dangerous to act over a multi that can have a strong option but you can lessen that risk by passing and bidding on the next round after the hand type has been revealed. Possibly the regulation is just intended to facilitate that.
So I'd interpret the regulation as meaning responder can pass with xx xx xxxxxxx xx but not with the given hand.

- I presume that directors are reluctant to enforce regulations that serve little purpose. But until they are cancelled, should directors enforce them?
- Assuming, however, that such regulations are enforced sporadically or not at all, should the EBU make it clear that players may interpret them with a large dose of salt ie "judgement". Otherwise directors and their confidantes have a considerable advantage over naive players, who slavishly and masochistically conform to the rules.

Further, a semantic point, 11G6(b)(v) uses the term "is expected to" not "must" or "shall" - this choice of words could only have the intent of not making it mandatory to explore game.

I play multi with some of my partners. We have always interpreted this Orange book directive to mean that responder is expected to explore game possibilities if his hand justifies it opposite the stronger options of opener’s Multi 2♦ (without qualification so that it applies even if responding may be a disaster opposite a weak option). We have suffered many bottoms as a result
An opponent held this hand yesterday and passed his partner's Multi 2♦. My partner asked for a ruling. 2 Questions ...
