1-(3)-?

Is this hand good enough (and otherwise right) for a negative double?

I have intentionally left out the form of scoring, if it makes a difference, please answer for IMPs and MP.

Please also mention if it would make a difference if 1 is limited to 10-15 (Precision-like) or 11-17 (Polish-like).

yes, though I think you have to push this hand much like you would with a Limit Raise hand having to bid game instead of the normal LR. For example 1 (2) where 3 is now a constructive raise.

Double. All vuls, all forms of scoring. There is much to be said for the principle that he who is short in the opponent's suit stretches to act.
Please let me know about any questions or interest or bug reports about GIB.

Yep, and I don't like it unless it works --but gotta.

Anyone want to give up on a natural 3NT here, and use double for a more convertable hand and 3NT for this one?

Yes, double is clearcut.

No thanks.

I'd rather bid 4 than 3NT.

double is not perfect but there is no option.

I'm assuming that the negative doublers (everybody!) expect the double to lead to 4 on a 5-3 fit with some frequency. What considerations go into opener's choice of whether or not to bid 4 when he holds exactly three hearts?

I'm guessing that with a spade stopper along with the three hearts, opener would tend to bid 3N. Certainly with a non-Ace stopper such as Kx, Kxx, QJx. What about Ax or Axx?

Does the quality of the three-card heart suit matter? Without a spade stopper, what is the typical minimum three-card holding with which opener would bid 4?

I won't pass 3N after double, I would bid 4. Double does not promise 4 hearts so I think partner will bid 4 with 3 hearts very rarely.

I don't expect partner to bid 4 with three, and I'll pass 3NT if that's what he bids. That might be right opposite three hearts, or even opposite four.

We might belong in 3NT, 4, 5 or 5, or it might be right to defend 3x. Double at least gives us a chance of getting to the right contract on these hands.

If we were to bid 4 over 3, we'd increase the chance of getting to 4 when it's right, but eliminate the possibility of getting to any other contract. That seems a bad exchange.

Double followed by 4 is a possibility. That suggests flexibility, but I don't think the hearts are good enough.

We might also belong in 4 or 4. Are you saying that you will be driving to game if opener bids 4m over your double?

Won't opener very often have a balanced 12-14? I don't think we should be too optimistic about making 3N or 4 (unless we have a 9-card fit), nor can we be particularly confident about beating 3, when opener has sort of what he's expected to have. Maybe you're saying that -50 or -100 is the result we're aiming for against a making 3, or at least that this is a possible way doubling can win even when we go minus?

I hadn't really thought about it, but I'd probably raise 4 to 5. I'd pass 4.

What of

S-xx
H-A98xx
D-Qx
C-K98x

still in negX ? Keep going lower hcp/shape until pass.

What higher until 4H? 4C?

I have no <13 hcp hands in 1D, so bottom strength combined is known or likely. Thus I can judge are we being preempted out of a game? Or did 3S get to their partial hoping we overbid/misbid?

No, would have opened 1NT. Isn't that part of the reason we agreed to play weak notrump? That is, to give responder more confidence in these auctions, knowing that 1x = a good suit or a good hand.

This is the only action I can think of; a sort of three-places-to-play 4. Come to think of it Double and pull 3NT to 4 must be three-places-to-play as well.

Perhaps that is what you have here, and pulling to 4 would be more like

x AKTxx xx QJxxx.

Interesting problem.

Interesting... You may keep the same HCP but vary the shape. For example ....
  • - Axxxxx Q Kxxxxx
  • - Axxxxx Qx Kxxxx
  • - Axxxx Qx Kxxxxx
  • x Axxxx Qx Kxxxx
  • xx Axxx Qx Kxxxx
  • xxx Axxx Qx Kxxx
  • xxx Axxx Qxx Kxx
  • xxx Axx Qxx Kxxx
Or you may keep the same shape and vary the HCP
  • x Axxxx Qx KQxxx
  • x Axxxx Qx KQxxx
  • x Axxxx Qx KJxxx
  • x Axxxx Qx Kxxxx
  • x Kxxxx Qx Kxxxx
  • x Kxxxx Qx Qxxxx
  • x Qxxxx Qx Qxxxx
IMO
  • a b = 4, c = 4, d e f g = _X, h = _P.
  • i ii iii iv v =_X, vi vii = _P
It might also be interesting to learn the effect of varying intermediates, honour quality, and location.
I agree with Paul that if partner rebids 3N, you should probably bid 4

Double for sure. My only problem is what to do after 3nt from partner; 4C and 4H are both possible imo.
After generating some layouts I believe 4C after 3nt is winning action.
We can still have 6 hearts for double and 4H right ?
