Hi everyone.

what is your opinion about hiding a minor second suit as responder and bidding 3nt instead ? will you ever hide a 5 card suit, 5431,5422 ?

thanks in advance
Sharon

It obviously depends somewhat on the form of scoring. That said, I will very often hide a 5 card minor to bid 3NT. If I show a minor, it is usually not out of fear for 3NT. It is at least a mild slam try. (But a control rich 11 HCP with a red 5-5 is enough for a mild slam try.)

I'd never hide a five-card minor. With a 5422 or 5431, playing standard methods I nearly always show the second suit, because I expect my partner to pass 3NT much of the time that he has a 4333 shape.

I prefer to play methods where I have two ways to show five of a major and then bid 3NT: one of them says that partner can pass with a 4333, and one says that he can't. Playing those methods, I'm more likely to suppress the second suit.

I don't regard showing a second suit as a slam try of any sort. With QJ10xx xx AJxxx x I bid 3♦ because I want to reach the right game opposite Kx AKxx KQx xxxx or Kx AKxx xxx KQxx.

5-5 are not very good in 3NT, when you have to develop 2 suits to get to 9 tricks and the opponents only have to develop one to put you down you are the underdog, they are on lead first!

[jophorst]

Personally I don't like showing minors when having only four of it. I already have learned that an 1NT-opening often can be done on two 2-cards (either 5-4-2-2 or 6-3-2-2). So even a 5-5 doesn't guarantee a fit.

Another interesting question is how to show your minor suit. I'd like to show it by bidding my other minor. That increases the odds the 1NT opener becomes declarer.

[Free]

With a 5422 I prefer not to show the minor unless I'm interested in slam.
With a 5431 I'll usually show my minor, because I can pattern out and partner can decide if we can make 3NT. Exceptions are obviously singleton A/K/Q.
With a 5-5 I'll always bid my minor, just to find the best spot.

Thanks everyone
We agreed on something close to what Free said.

Again, I'd like to promote Keri as a responding system to 1NT, which allows you to do all of these things.

1NT 2D 2H 2NT = GF, 5H 4m (with continuations asking for a shortage in responder's hand, allowing you to find a 5-2 major fit if required, a 4-4 or 5-4 minor fit when 3NT isn't playable or 3NT when it is.
1NT 2D 2H 3D = GF, 5H 5D

It's not terribly interesting as the answer is quite obvious: transfers.

[Fluffy]

When you play transfers you have a problem with balanced invites that have to go somewhere else in your system, you can cope with that in some ways.

I never played transfers so can't tell how good/bad they are, I will just show what pairs Goded-Lantaron and I think Fantoni-Nunes play, as far a I know it was developed by Belladona very long ago:

1NT-2♦ = 5♥ or 5♠-4/5m and a singleton
2♥ = forced

1NT-2♦
2♥-2♠ 5431 relay (can also be 5521) showing any 5M, and any 4+m
2NT = forced

after 2NT responder bids:

3♣ = 4+ clubs singleton diamond
3♦ = 4+ diamonds, singleton club
3♥ = 5♥, singleton spade
3♠ = 5♠, singleton heart.

[Zelandakh]

The simple rule I learned is that you show the minor if you are willing to commit to 5m opposite a fit. Nowadays, with transfer rebids you can more easily show the minor without making a commitment but I think the concept is still valid. If you would never be interested in 5m (or 6m) then there is no reason to show it.

As for how to show the minor, over hearts this is easy. As long as you bundle your balanced invite into 2♠, you can organise the other hands via transfers. One popular option is for 2♠ to show any invite and to limit Opener's acceptance in such a way that the right contract is reached if Responder has a 5♥5m hand instead. Another is to include clubs in the 2♠ rebid along with the balanced invite and for 2NT to cover another awkward hand (such as a 5♥4♠ invite). What you use here will depend on what you had space for elsewhere in the structure.

After a 2♥ transfer this is harder. You are pretty much stuck with either natural or inversion. There are other solutions, as Fluffy points out, but they are more complex and usually involve making bigger changes to the NT structure than most players would be interested in.

Well, yes, I guess most players are not interested in making any changes at all. Having 1NT-2♣-2red-2♠ be an invitational hand with 5 spades doesn't seem to me to be a very big change to most Stayman structures though (and as an added bonus you sometimes get to play 2♠ on a declined invite).

It may not be a big change, but it has significant costs: it wrongsides spades, leaks information about opener's heart length, and means we sometimes get to the wrong contract when responder has a signoff with five spades and four hearts.

[PhilKing]

Play transfers as invitational or better. This helps massively on a concealement basis - You play 2 articial transfer breaks, one showing a full max with two trumps and one to show a non min with a three card or better fit. Responder can just retransfer and bid game, or explore further if he desires. Usually the defence end up known very little about the shape of either hand.

Sign-offs are shown via reverse Stayman - opener bids the major he does not have. This gets you to 3♥ when you have a 5-4 fit, but opener would usually have broken a transfer anyway.

Or play transfers as signoff-or-strong, and free up the 1NT-2D-2H-2NT/3H bids for new kinds of GF hands (like gnasher's distinguishing hands where opener has a choice on 4333 or not).

Admittedly works better when 2C is more Keri-like than when you are shoehorning hands into Stayman. But I could live with 1NT-2C-2D-2M as invitational with 5 like it was in the Goren days.

Wow I can't believe this trade-off is worth making. A sign-off in 2M is one of hte most frequent auctions over 1N IMO.

We still get to sign off in 2M.

It gets you to 3♥ when you have a 5-4 fit, it makes garbage stayman (an enormous winner when it comes up) impossible, it gives them extra artificial bids to double by both players, it prevents opener from super-accepting for either major (btw I strongly disagree with the idea that opener usually superaccepts with four in the major - it's still a clear minority action), it prevents you from competing effectively if the next opponent interferes (1NT p 2♣ 2♠...), and you lose whatever stayman followed by 2♠ was. That is what I thought of in the first three minutes of thinking about that convention. That is not "almost no trade off". If I ever played it I'm sure I would see all the good things it does, and more bad things as well.
(Edit - it wrongsides the major suit signoff, it loses the invite in hearts or some other bid after stayman since 1NT 2♣ 2♠ 3♥ is a signoff...)

It seems so unnecessary and pretty complicated to boot. Of all auctions, ones that start 1NT p transfer seem to be the least of my problems.

I have a little more experience against Keri and have seen it perform absolutely terribly. It gets you to so many bad 4-3 fits that I'm certain that one disadvantage overrides all advantages combined.

Who doesn't get to three? Most people break with four hearts 80%+.

Not quite, although it's a bit more of a gamble. We still bid 2♣ on a 4351 or a 3451 and punt a pass if partner open bids our 4-card major or bid 3♦. We gain outright when responder has a sign-off with 4M and 6m and hits a fit getting to an unbiddable game.

Not extra - just a different one. And if second seat wants to double after 1NT-p-2c-p-2h, then he is probably in a world of hurt.

it prevents opener from super-accepting for either major

When partner shows four of our major, the hand that knows what to do is in control - not vice versa. Outright gain, surely.

(btw I strongly disagree with the idea that opener usually superaccepts with four in the major - it's still a clear minority action), it prevents you from competing effectively if the next opponent interferes (1NT p 2♣ 2♠...),

OK - you personally are exempted from auto 3M auctions. So am I when the 54 fit is spades. Responder is in control.

If you play garbage Stayman, you can't compete that easily anyway.

and you lose whatever stayman followed by 2♠ was.

This is a gain compared with those who play Stayman followed by Two Spades invitational for the reasons Gnasher gave.

That is what I thought of in the first three minutes of thinking about that convention. That is not "almost no trade off". If I ever played it I'm sure I would see all the good things it does, and more bad things as well.

It's really simple - promise!

In England, most people who play Keri are pretty ordinary. Maybe it's not that bad.

80%? I didn't realize Britain was a different planet than the US but it must be. I would have said 20%. I super accept when I am worried about missing game or slam if I don't, not to announce to the world I have four cards and get higher than I have to. I'll try a Bridge Winners poll.
