BBO Discussion Forums: 1D - 2D - 3NT - BBO Discussion Forums

Yesterday we played a pair where opener was 3-2-4-4 with 19 points, and opened 1♦. After his partner's 2♦ (with 8 points I think) opener bid 3NT which went off. Opener had just ♥Qx and his partner had ♥xx.

We have just started playing inverted minors where, after 1♦ - 2♦, we start cue bidding stoppers for 3NT investigation. Is there anything like that for this situation or do you just bid 3NT and accept that every now and again you will be unlucky?

Well, this is a Canadian speaking, so SA-centric; but new suits after suit agreement are forcing (except where screamingly obvious), and the primary goal with a minor fit and game-going values is "look for 3NT". So, it seems "obvious" that 2M after 1♦-2♦ would have a similar meaning opposite a 6-9 raise as opposite a limit+ or GF+ raise, it's just that opener has the strength that responder lacks.

This is doubly true if 1♦-2♦ denies a major, which (given that it's passable, and frequently passed) is an even better idea in standard than in inverted. Unfortunately, very few good players don't play invm of one sort or another, and the weaker players may not have that ingrained yet.

So, it's more dangerous here than if you've agreed to play invm, but not because it's any different; just because the invm players have discussed this (with somebody, anyway) and are less likely to get it wrong.

Having said that, blasting frequently works - when opener has 8xxx for instance, and doesn't get the lead from Kx into AJxxx that if you show stoppers you've telegraphed.

If opener with ♥ Qx was opposite Kxx or Axx, he wants to play 3NT from his side. If you have a stopper showing auction, the opponents know what to lead, even if you wind up in 5D. I'm a blaster and sometimes it don't work. It just has to work more often then the alternative.

Hi,

the inv. raise is forcing to 2NT or 3D, major suit bid show stoppers.
Given that 2D denies a 4 card major, you know, that they have a 8 card heart fit,
and a 7 card spade fit, so trying to see, if you have a heart stopper is certainly
not a bad idea, but blasting will also work.
The main problem with 3NT is, that you cut done any chance to investigate 6D.
After 2D, opener knowes, that most of the time, the partnership has 30+ points and a
fit, quite often a 9 card fit, what stops you from investigating 6D, without commiting
your side by bypassing 3NT? Add to this the advantage, that you avoid 3NT sometimes ...

Finally 8 is a bit light for a 2D bid, even in a weak NT context, it should be more like
9.5+.
With kind regards
Marlowe

Hi Marlowe,

sorry I wasn't clear enough with my post.
The pair that went off don't play inverted minors. We do, so with the same hands my partner and I would have bid 1♦ - 3♦. I was wondering whether there was a way for us to check for stops like we do after 1♦ - 2♦, such as: opener bids 3♥, showing a heart stop and asking for partner to bid 3NT with a spade stop, or bids 3♠, showing a spade stop and asking partner to bid 3NT with a heart stop. or some other device.

I take the point that by doing so you telegraph where your strengths and weaknesses lie, so it might be better just to blast to 3NT

When considering whether or not to blast 3NT on a hand like this, the main consideration should be whether your side is likely to have a better alternative contract.

Holding a balanced hand, the answer is usually "no". Even if 3NT can be defeated by accurate defense, it is still a better chance than making 11 tricks in Diamonds.

The same principle applies when considering whether you should explore for an alternative contract after partner's 1NT opening. Exploring for a major fit is usually correct (because 4M will often be a superior contract to 3NT), but without extreme shape or serious slam interest you are usually just blasting 3NT rather than exploring for a minor fit.

Playing standard system ,without any fancy gadgets,since 2 D shows a limited hand ,there in no safe way to avoid 3NT with a 3244 balanced hand.Just bid 3NT go down and forget the hand. No one can see but partner may produce Kxx in heart.Or in some deal even J xx may suffice.

Agree with Wesley's comments. I blasted once with xxx H and Q well guarded. Partner also had xxx H and after I lost the first 4 tricks, I made all the others. Obviously, 5D is off... So unless you have substantial extra strength or shape that may allow for 11 tricks, aiming for 3NT with "limited" and balanced material is surely best. Blasting or cueing is a matter of partnership's style, and all contributors mentionned the pros and cons of each method. Personally I use both.
On the hand you gave, a positional semi-stopper like Qx would probably tempt a lot into blasting in order to right-side the contract.

Story time. I open a no trump with ♠ AJTx ♥ KQXX ♦ KXX ♣ QX at a real important tournament, pass, partner bids 3 diamonds invitational and 3 spades on my right. I wasn't going to accept but with a spade lead I'll try it. 3NT by me. Partner has ♠ xx ♥ Jxx ♦ AQTxxx ♣ xx. Spade lead to the queen ace. King of hearts, everybody ducks. Queen of hearts, everybody ducks. Six rounds of diamonds.

Here playing a weak NT has an advantage, as 1♦-2♦-2NT is forcing. A useful gadget is that 1m-2m-next step is an unbalanced GF (not applicable here, but does aid in finding slams).

As we play inverted minors, on this hand the bidding would go 1♦ - 3♦, so for us the choices seem to be to blast to 3NT or cue bid for stops in the majors.

Is your inverted minor forcing to game or merely forcing for one round (ie what's the max for 3♦) ?

We play that after 1♦, 3♦ shows a minimum raise (6-9 points) and 2♦ shows 10-12 points and is forcing to 3♦.

A problem with inverted minors is that the 0-9 range for a 3m response is too wide and too high for invitational sequences. A solution is to make the 3m bid mixed raise type, and use 2NT as your weakest raise. Maybe reversing these is better; I really don't know.

I don't see anything wrong with the auction. As little as ♥Jxx or T9xx opposite is enough, and even lacking that they don't always lead the suit. If you never go down you aren't bidding enough.

Liversidge, on 2016-May-05, 08:37, said:

Do you mean 10-12 or 10+ ? it's a bit wasted as 10-12.

OK, 6-9 then you don't have the problem that partner with a flat 19 is worried there might be a slam on enough of the time to have to think about it.

My inclination is to just blast 3N particularly at MPs where pinpointing the lead may get you a poor score even when 3N makes.

OK! 10+

Vampyr, on 2016-May-05, 09:21, said:

My preference is for 3m to be the weakest raise and jump shift in other minor to be the mixed raise.

We use 2N as a raise to split the 0-9

I don't think this is anything to do with weak NT. I play 15/16 NT, and 1♦ 2♦ 2 any is forcing, but this is with an unbalanced diamond, not a better minor type.
