Yes, it does spill information, but gets us to the right contract played by the right hand. I think the trade-off is positive.

I can't remember the last time I wanted to stop in 3M after a 2NT opening. If it happens I'll live with playing in 4.

In my methods, we transfer to hearts with 5+, regardless of the spade length. If opener only has 2 hearts he shows the spade length (3 is 2 hearts and 3 spades, 3 is 2 hearts and 4 spades while 3NT is 2 hearts and 5 spades). With 3+ hearts, opener rebids 4 to show exactly 4 spades(allowing us to find the possible 4-4 fit) or bids 4 with any other spade length.

Responder's next bid (except over 4) is a transfer. With the given hand, if opener shows 2 hearts, we bid 4, forcing opener to bid 4 after which 4NT is keycard on spades.

So, we always find the 5-3(+) fit and always right-side the contract. Transferring to spades and bidding hearts wrong-sides a heart contract.

@Ed. Your 5 bid is by responder who doesn't have 1st round control. Did you mean 5?

I have played several varieties of multi (but never the weak-only version in the OP). Our rule has been that responder's first action, if in a suit which might be held by opener, is always pass-or-correct.

Sometimes it is obvious that opener doesn't have that suit, but the rule saves a lot of confusion.

I have played 11-14 for many years.

Adding 11 to a 12-14 range means opening 1NT 40% more frequently. It doesn't change anything in your basic structure, you still invite with 11-12 and accept with 13-14. Actually accept with a good 12 and a good 5-card minor, decline with 4333 13 with no stuffing. As others have said, 11 opposite 11 plays much better than 15 opposite 7.

One big advantage is that third seat knows that a passed partner does not have a hand worth inviting over a 1NT opening. So you know partner will pass unless very shapely. This allows you to do interesting things with 1NT in 3rd seat. Our card reads

1NT: 11-14 1st & 2nd, 9-14 may be off-shape 3rd, 12-14 4th.

I hold 2=2=3=6 9-14 points, not vulnerable. If I get two passes to me, I'm opening 1NT every day of the week.

You do need a good escape mechanism from 1NT doubled, but there are many options out there. Everyone has their own preferences, so pick one which suits.

If you want, email me tony at gillandtony dot com and I can send you a pdf of the scheme.

In summary,

2NT - 3 is Muppet Stayman (Puppet with the 3 and 3NT responses swapped)
2NT - 3 shows 5+ hearts, spades may be longer
2NT - 3 shows 5+ spades and up to 3 hearts (opener bids 3 with 2 spades and up to 4 hearts, 3NT with 2 spades and 5 hearts)
2NT - 3 shows 5+/4+ minors, GF. Opener shows a 4Cm or bids 3NT without one.

The only time a transfer wrong-sides a major contract is when opener is 2 spades, 5 hearts and responder is 5 spades, 3 hearts.

After any of the above, responder's second bid, if at the 4-level, is never the real suit and almost always a transfer.

for completion

2NT - 3NT is a single-suited club slam try
2NT - 4 is a single-suited diamond slam try
2NT - 4 is exactly 5 spades, 4 hearts with slam ambitions.

Thanks for that information.

I'm happy with using the 1M rebid to show all 4+ support strong hands as it gives a lot of room to explore. The question is how to explore?

When I transfer to hearts, pard tells me how many hearts and spades he holds. I then transfer to the appropriate Major and pass or bid on as appropriate.

After 2NT - 3 pard bids

3 2 hearts and 3 spades
3 2 hearts and 4 spades
3NT 2 hearts and 5 spades
4 3+ hearts and 4 spades
4 3+ hearts and not 4 spades

With the given hand I bid 4 over any 3-level response and pass pard's forced 4 bid. This always right-sides a contract in either Major. Transferring to spades and bidding 4 wrong-sides a heart contract.

I play:

11-14 open 1NT
15-22 open 1 (forcing with transfer responses)
23+ non-forcing (needs a Queen to accept) Open 2NT
23+ forcing 2 - 2 - 2NT

After 1 - 1 red, 1NT is 15-18 and 2NT is 19-22 GF
After 1 - 1 (negative) 1NT is 15-20 and 2NT is 21-22

Surprisingly, the 15-20 rebid works very well. Responder almost always passes and then the wide range doesn't help the opposition. We do have ways to invite, but invitational hands with any suit except diamonds won't be here.

After the 2 sequence, opener is unlimited and we do have ways for opener to take control when very strong.

Thanks to all who contributed.

I agree with Kieran that pass is not comparable for the reasons he gave.

I don't agree with Esko when he said “Based on your reply above, you seem to confuse the sets and the subsets. Assume that the range of 2♠ is 0-13 hcp. If the range of X or 3♣ would be 7-13 hcp (or even 12-13 hcp) that range would be the subset of the 2♠ range”.

Certainly 3 could be limited to a subset of the range of the 2 bid, but double could be considerably stronger. With something like Ax,x AKxxx,AKxxx I would happily double. If partner has spades then it could be very expensive for the opps and if he has a minor we could be heading slamwards.

The thing which struck me is that if a host of very experienced directors have varying views what chance is there that a club-level director will get it right?

Thanks again all. It was a very interesting set of responses - very thought provoking.

How would non-cuckoo work after a 2 - 3 pass or correct?

Given that these are moderate club-level players, I think it would be cuckoo to have two different sets of rebids depending on whether it was a 2 or 2 opening.

My reasoning was that 2 could be made with zero points, but 3 or double would be free bids and would not be made on zero points. Thus they are not subsets of 2. I wasn't sure if they would come under options 1 or 3 (the same or similar meaning), hence my question here.

Here's another question.

You pass when partner is dealer. You hold 6-9 HCP, 4 spades, 2 hearts and 43 minors. Pard now opens 1 and RHO passes.

1 is not comparable, so are you allowed to bid 1NT, denying 4 spades, or 2 promising 3 card support? Or must you make a correct systemic bid?

If I have 0-1 in their suit I balance. With 3 or more, I pass. With 2 I make a decision based on the rest of the hand. If I have 3+, then either partner is short in their suit and not strong enough to double or overcall or pard has length in their suit so RHO is short and they are in a bad place.

If the offender makes a weak jump shift, particularly in a Major, it does not deny a hand which would have opened with a weak 2. Is a WJS comparable to a pass out of turn?
