2/1, all jump shifts are weak.

1-1NT (forcing)
3-4

What would most advanced partnerships play 4 as?

1. Natural & forcing (x xx Axx KQTxxxx)?
2. Cuebid in support of hearts (x Qxxx Kxx AQxxx)?
3. Assumed to be 2 unless the suit is rebid at the five level, then 1?
4. Natural and nonforcing?

Feel free to weigh in on 5 as well over 3, and whether that is natural or a heart splinter(Exclusion if applicable).

Cuebid, but with an unknown partner or a reason to doubt the agreement I hope people wouldn't torture each other by cuebidding the suit twice...

Since 3 is forcing to game, and 4 is not game, you can get rid of your choice 4.
Please let me know about any questions or interest or bug reports about GIB.

Thanks for the link -- obviously didn't notice that before.

I don't think there was a concensus in the other thread for 4 .

One expert I know plays it as:
4C = natural, non-forcing... long Clubs .. BAD hand
( not wanting to play in 3NT, Sp or Hts ):

"No fit for one of Opener's suits, you don't want to go
above 3NT unless you have a weak, long suit and the only way to get
tricks out of it is if it were trumps ".

Others I know play 4 as an advance cue for Opener's 2nd suit, .

natural and forcing. We're only tempted to want this for a cue bid because unlike 1S-1N, 3D-4D, the raise to 4H is not forcing.

However, we can't get around that it's bad for one partner to be able to show a two-suited hand while the other can't show a single-suited hand...especially when he can have invitational strength.

In a context where 1-3 is weak, what sort of hand would want to bid 4 natural?
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

Going past 3N seems dangerous with this hand, though you may have a club slam, you also may have a misfit that can make 3N on power.

Having no way to raise hearts strongly is really absurd though, for every hand you have that you want to bid 4 of a minor (I don't deny that they exist), you have 20 that wants to show a slam positive hand for hearts without having to just bid 5H.

I agree with all that, I just wanted to say that there is a distinct class of hands that, though being in a minority, would wish to bid 4m naturally.

If someone plays 1S-1N, 3H-4C as agreeing hearts, then that's fine but it's a conventional treatment and not a natural treatment.

That auction is obviously quite a bit different than 1N-2H, 2S-3H, 4C where opener can't want to show clubs.

As long as the partnership is interested in a conventional treatment for this specific sequence (because other similar sequences such as 1S-1N, 3D-4D are not problematic), then one might look at using a 3S rebid as a relay...probably a weak relay.

1S-1N, 3H-3S (weak), 3N (no extra distribution)-
.....4m-weak, bailout
.....4M-weak, fit

but
1S-1N, 3H-3N shows a good hand with no fit
1S-1N, 3H-4m shows a good hand with a good suit
1S-1N, 4M-shows a good hand with a fit

That's off the cuff, but that 3S bid is underutilized imo.

So you give up the ability to show/deny a doubleton spade in partner's suit to gain the ability to stop in 4 of a minor?!?

That's a bad trade, but I think that using it as a relay has merit.

How about...

1S-1N, 3H-3S, 3N-
.....4C-two-fit in spades
..........4H-5/5
.....4D-medium hand for hearts
.....4H-weak hand for hearts

1S-1N, 3H-3S,
.....4C-7/4
.....4D-6/5
.....4H-5/5 stronger
.....

1S-1N, 3H-
.....3N-good hand, no fit
.....4m-good hand, minor
.....4M-good hand, major

3 is definitely strong, so hopefully yes. :)

I was responder and had:


T9x
KQT9xx
Q7xx

I raised 3 to 4; partner took another chomp at the apple by bidding 4 with:

AKJ8xx
AKQ6x
x
x

If I had something like the hand below, he'd want to be in six:

x
J9xx
Axxx
xxxx

In this case, 5 was too high. I suggested 4m was a cuebid for hearts so I couldn't hold that hand; partner didn't think so and I was surprised that the two partnerships I queried also didn't think so, but agreed with Pavlicek's definition.

Thanks everyone for the input -- much appreciated.

There's that rule about never raising partner's second suit with fewer than four.

But if you had a weak relay (3S) available...

1S-1N, 3H-3S, 4D (6/5)-4H now partner knows you're weak at least.
