for south, 3N or 4S?
if 3N, should north correct to 4S? |

发帖数: 6639 | 2 i would bid 3n, and also correct to 4s.
not sure why 3n (instead of 4s) is even a question when south only has 5 spades.
but i'd like to hear opinions on both options.

发帖数: 3277 | 3 yes, north should bid 4S because C is weak. North should pass 3NT
only with doubleton or 4-3-3-3, 3 baby spades and good side suit stoppers.
like:
Sxxx HKJx DAQxx CAQJ.

发帖数: 2168 | 10 hehe this is what my pd told me after he passed my 3N and went down.
It's a correct choice for 5-3-3-2 vs. 4-3-3-3 he said. There are 5 sure spade
tricks and no ruff values, so 3N is better.
But I tend to agree with cozofu that 4S is more reasonable because of the weak
spot in clubs.

totally empty. switch your minor holding, i.e
S AJ8
you have no way to differentiate these, still wanna in 4S? or 3NT?
if diamond K off, 4S has little play, not mention a possible club ruff.
but 3NT really needs no play.
The principle is when there's no ruff value, 9 tricks is easier.
principle is principle, luck is luck. Don't be confused.

发帖数: 3277 | 12 well, even in this layout, 4S is still a reasonable contract.
Just imagine how bad 3NT can be when partner holds something like:
SKQTxx HAQx DKxx Cxx,5S would be cold and 3NT goes down on a bad day, whose
fault? 3NT have good play only when partner has marginal values and
some specific high cards, while 4S would be better than 3NT whenever partner
holds Cxx. even CQJx may provide 3NT a better play.
Also, some play 2NT over 2S as gameforcing and asks for detailed distribution,
which might work we

发帖数: 3277 | 15 No. It's very important to place 3NT or 4S. Only relay can solve this problem.
As I've said again and again, positional issue is a minor thing comparing
with distributional information. I'll post a detailed solution for this
sequence.

problem.
agree with this. i note that many ppl on bbo discuss xfer and so on, mainly on
right siding the contract. i think natural bidding will solve this problem
most of time.
I'll post a detailed solution for this
if opener want to know more to decide where to play, then perhaps it is better
for the responder to tell his shape rather than opener to tell.
so if 2n is gf, then it should show exactly 5332, then 3c ask which suit is
doubleton, then 3n says it is club.
1n 2h
2s 2n(5332)

发帖数: 17 | 20 Bidding is not playing, it is convention between partners:
3NT here means clearly 5332 10 or so HCPs.
Pass 3NT means 2-3 S, stoppers in other 3 suits.
4S means 4 S support (another form of "8 never, 9 ever" :))
The rationale behind this is. unless 1NT hand can ruff something, 4NT can be
made if 4S can be made in most of cases, but 10th trick might make hugh
difference for a 3NT hand with 4S bid.
The question here might present an opposite example, but in a long run, it
would be benefitial to fol

发帖数: 17 | 22 Good point. Qxx is only half of a stopper. North can only hope South has Jx or
better because after transfer, South drives the bids.
That brings a subtle disadvantage of strong NT/transfer convention. with big
club bidding systems, for example, after 1C-1S, strong hand openers can
control the bids afterward.

发帖数: 3277 | 23 Qxx is not a half stopper. A half stopper is Qx or Jxx.
Also, for strong club systems, it's not always the stronger hand
taking control. And this is not even a disadvantage for a strong NT
system if one is really ambitious to refine his system. There
are a lot of room to improve still.
