I've recently decided to come back to this response structure over 2NT showing a strong balanced hand:

3 Muppet Stayman
3 Hearts
3 Spades
3 Puppet to 3NT, to play there or single-suited minor slam try or slam try with both minors
3NT ???
4 Some form of ace ask unless there's a better suggestion
4 Hearts
4 Spades
4 ???
4NT ??? (Quantitative could also be handled via 3)

Given this scheme, what hand type would you want to put into 3NT (and 4 and 4NT) if you were confident that you and your partner would not forget it?

Just spitballing...

Perhaps you have seen this writeup, which uses 3N to show unequal minor lengths with slam interest. I have yet to actually bid it in my partnerships, but it seems sensible enough. They give you an escape in case responder forgets, which is thoughtful.

I prefer South African Texas (4= 4=), in part because I detest Gerber passionately. Depends on your follow-ups to Jacoby transfers whether this is worth adopting or not, in addition to the potential of utilizing a direct 4/.

If you give up Gerber and still want a direct ace ask, perhaps
2N-
4 quantitative w/ even amount of aces
4N quantitative w/ odd amount of aces

But I have not pursued that issue in depth.

Just find a hand that you can't bid and see if 3N/4!C works for those hands. 4/ 6+/ comes to my mind as a headache. Perhaps
3N-> 4 (drop or FG)
and
4-> 4 (drop or FG)

now you can make 4M here 4-6

Also this makes use of 4/4N pretty well.

Thanks very much for the link, which I had in fact not seen before.

I too used to detest Gerber, but after http://www.rpbridge.net/8j25.htm convinced me I should be going to 6NT with 31 HCP I have started to appreciate it more. I do like the 4/4NT quant idea, thanks for that.

If you haven't got any better use for it, use it as a natural signoff.

I can't answer your question. But in chorus with at least McKenzie Myers, I would strongly recommend that whatever 2NT-3NT means, 2NT-3NT; 4x-4NT means "I forgot again, partner!"

I play this structure and we just play four way transfers (3N=, 4!C=). We fit in all the hand types and can do all two-suited Majors and all two-suited Major minor slam tries. People are perfectly happy to play 1N-2N as artificial so I don't see what the big deal is with 2N-3N. PM me if you want me to send you a copy.

We play 4 as "pick a major" and 4 as ace-asking. Puppet to 3NT and then 4NT could be a slam try with 5-5 in the minors (if your other ways show 5-4).

Play the same thing but 5s3h hits a seam in regular Muppet so in one partnership 2N 3N shows that.

How so? Or do you mean 3s5h?

Best possible use of 2NT-3NT = "Let's play 3NT"

Now 3 can be a minor suit slam try, with 3NT as opener's default bid, but opener can bid higher to show suitability for either or both minors. Say 4=like clubs, 4=like diamonds, 4/4=Qbid (Ace) liking both minors. 4NT=likes both minors but can't bid 4M, is one possibility that isn't too hard to remember.

I would just play it as "to play". Something like

3 =clubs,opener can then bid 3NT so deny interest in a club slam.
4 =diamonds
4 = 2155
5 = 1255 NF
5 = 1255 F

This make it uneconomical to bid both minors but since (31)(45) start with PS anyway it just means that a 22(54) will have to settle for a notrump contract.

That is a disadvantage but allowing them to make a lead-directing double on 3 whenever you just want to play 3NT, or forcing you to go through PS which leaks information and allows them to double 3 (and maybe also double some follow up bid) is worse, IMO.

I have written up what I do (similar to Helene's suggestion) many times but you probably consider it paper bridge and not fit for real play.

3NT could be a mild slam invite asking for a five card minor. Opener passes without 5(+) minor, otherwise bids it and slam bidding commence.

Just an idea:

2N-3N = 4S5H, NF,

because it allows

2N-3 = 5+ H or bal.(?) slam try

with similar continuations as I suggested after 1N-2(5+ H or bal.(?) slam try*) in post #10 here:

http://www.bridgebas...627#entry869627,

i.e.

2N-3; ?:

3 = 2-3 H or 3433 (=> 3 = relay, cancelling the transfer)
3 = 4-5 H, not 3433 (=> 3N = relay, cancelling the transfer)

* similar to, and quite possibly inspired by, glen's Jacoby Stayman

If you use second round transfers you can use the sequence 2NT - 3; 3 - 3NT for this. 54 tends to be more of a problem hand if playing the common form of Puppet Stayman and this is a popular option (aka Beer convention) but the OP plays Muppet so that would also be fairly pointless. If you want a balanced slam try below 3NT, it seems more sensible to me to use the 3NT response itself for it; at least that is unlikely to be too costly if forgotten.

3= transfer to ; may be weak or strong
3NT = 5- 4
4=transfer to , may be weak or strong
4 = Ace asking, CRM (1-4, 0-3, 2 same colour, two same rank, two mixed)
4NT = quantative, 5 and 4
