A sequence came up that seemed odd and unexpected, perhaps because of what I was looking at. I mean, I could not have the hand I had for the sequence to make sense. One of those hands.

Anyway, just to make sure that I am not completely insane...

Suppose you open 2♣ strong, and partner bids 2♦ as a GF waiting bid (at least two Queens or a King). You now bid 2♠, and partner bids 3NT.

What is 3NT?

[MarkDean]

I think pd has Tx KJ9 QT9x QT8x

[Free]

2=3=4=4 with 2 Queens.

With more strength or better shape, he'd bid 2NT.

Same, if he bids 4♠ he'll have 2 Queens and nothing else of value.

[CSGibson]

No controls, no 5 card suit, no spade support, but slow stops in every other suit is my opinion.

somethink like x JT98 QT8x QJ9X, imo.

Since there can never be a reason to bid 3N as natural, when opener is unlimited and may have a second suit, it is clearly ( ) an artificial raise of spades. Hmmm, the most space-consuming raise would be a splinter in hearts. So that's it. 3N shows short hearts, good spades, and some interest in slam.

Wasn't that easy?

In reality, it means whatever you have agreed it to mean, but in my partnerships, it never happens....which takes me back to where I came in.....

yep. Important, IMO, not to jump around with even one king. Also not to bid 2NT in response to 2C with a king, if you use that response at all in a natural sense.

[hrothgar]

Agree with MikeH. The bid can't be natural...

After

2♣ - 2♦
2♠

The set of bids (4♣ < -- > 4♥ can be used as a fit jump or an anti splinter or whatever you want

A 3NT bid shows a splinter in an unknown suit

Opener can relay with 4♣ and then

4♦ = Heart splinter
4♥ = Diamond splinter
4♠ = club splinter

[kenrexford]

In retrospect, I think I was in fact somewhat insane. But, I suppose I never even considered what this bid should mean without discussion.

I mean, the "fast arrival" idea (2344 with two queens) makes sense, IMO, as a "picture bid."

I can imagine that an artificial meaning also makes sense, if discussed.

My thought (maybe insane) was that this unusual jump in notrump seemed like a "mini quantitative" call. Descriptive (probably 2344), but a tweener hand, meaning the hand with which a 2NT call, followed by any call from partner, would cause a problem of whether to invite slam or not. So, you just hit 3NT like you would hit 4NT otherwise. Sort of what MarkDean proposed.

you can certainly play it as a splinter with a void somewhere. No point to bid a natural 3NT which take up a lot of space.

[dredog03]

I agree with ken and mark dean. Even without discussion, I to think jumps in NT do show extra values, even when you're in a game-force, so this 3NT would be quantitative-ish 8-10 or so hcp and approximately 2-3-4-4 shape. With the minimums and 11+ hands, you would start with 2NT.

[MFA]

If I were to propose a conventional meaning, I think I would prefer to have 3NT as a bad positive raise of spades, while 3♠ would then be a better raise.

[helene_t]

My first thought was a heart splinter but then I thought of something Schollie wrote in IMP: Over 3♠, opener's rebid is natural, as we would have a better fit in another suit, and even if spades is fixed as trump suit it is important to show shape. So may 3NT should be a 4-card raise.

MFA's idea is maybe best.

But without discussion I think it is natural. Not sure how strong it is, though. Tend to agree with MarkDean.

[dake50]

Disagree min bal. Just 2N, then 3N. No incitement.
Agree bal middling expecting problem rebid. Jump 3NT incites just a little compared to bidding out shape to see where partner has 'stuff'.
Then 4NT has 'likable' values after shaping out.

[jeremy61]

I think that any unusual bid must be fit-showing
In my partnership I play

3♠ = Good raise. At least one lateral control (Ace or King) and one distributional control (singleton or chicane)
3NT = Fit. At least one lateral control (Ace or King) and NO singleton or chicane
4♣♦♥ = Splinter. No Ace or King lateral

Over 3♠ or 3NT cue-bid can follow with some artificially to ask for singleton after 3♠
