5N 6C (2+ diamond void ; Q ask)

6D ? (yes)

 

South now knows north has a diamond void and 2+Q. What you want to do now maybe depends on what a 6H bid means to you, but if south had to place the contract, 7S is certainly a better guess than 6.

Not too tough, give south KJxx, xxx, xx, AK109 where you need to play 7♣ to make it hard :)

 

I agree with clee up to 4♦ but we play it rather differently as optional exclusion, so we bid:

 

1♠ (2♦) 2N (4-card inv+ raise)

4♦ 5♣ (2 without Q non minimum, 4♠ would be minimum)

5♦ (interested)-5♥(K)

5N (still interested)-6♣(K)

7♠

How do you show a singleton diamond? 3N any short?

Once the AK of clubs have been cue'd, It no longer matters if responder has third-round heart control...can go directly to establishing KXXX of spades.

We bid something else first. Yes AKQJxx, QJx, x, QJx we're a bit stuffed but as we play long suit style bids over 2N, we bid 3♣.

 

We play 4 card majors, so 3N would be only 4 spades, hence 4333 as we open the other suit with any 4-4 with spades.

1S (2D) 2N (4-card inv+ raise)

I 've been meaning to ask. When was 2NT adopted as a 4 card raise over new suit interference?

 

I'm only familiar with the cuebid showing 3+ limit raise:

 

1M - ( 2m ) - 3m!

Adopted by whom? The International Trump Raise Federation?

 

I've played it since before Roger was born, having been influenced by Oliver Segal, but the idea is much older. Obviously it appeared in book form in Partnership Bidding at Bridge, 1993.

Thx....Somewhere along the line I've missed this .

using splinter in a quantitative fashion with my own little twist

1s

2d overcall

3d limit+ spades no more opp bidding

4d splinter singleton or void

5h 12-13 outside diamonds (not including jacks) + a "ruffing" holding Ax or Kx

Jx or xx in hearts (with Qx you can't count the Q as part of the 12/13)

7s

1♠ (2♦) 3♦ GF in support of spades

3♥ 4♣ - control bidding

4♦ 7♠

 

Thinking if partner showed 1st round control of diamonds, instead of bidding 4 spades, he has A5th+ in spades, with AQ of hearts, we still see only 10 points to open. He could hold the ♦ A, and no club help, but then RHO overcalled on ? ? KTxxxx(x), QJx(x) - would he? RHO has to hold the ♦ AK

A 4-0 trump split would almost certainly be offside and they have to have the QTxx to beat us.

[biggerclub]

If I were partnered with me (Oh! what a glorious fantasy!), "our" bidding would go:

 

1S [2D] 3D [P]

4D [P] 5H [P]

6S [P] 7S [All P]

 

3D = LR or better.

4D = Void + Slam interest (Note -- NOT 3NT or 4S, so showing extras -- also by bypassing the whole 3 level, showing extra extras)

5H = Suit of concern -- can you help here?

6S = Yes I can (with no first or second round H control, would sign off in 5s; with 2 of top 3 would bid 6h or 5NT for some sort of super accept)

7S = I was trying for a grand all along with 5H and had "you" signed off in 5s, I would have bid 6s. Notice that it is impossible to construct a hand without the Qc for opener at this point. The missing high cards are: AQs, AQJh, AKd and QJc. Opener does not have any of the ds (4d recue) and does not have the Qh for the response to the 5h query, yet has a full opening hand for 4d recue.

 

Notice that no conventional treatments or understandings are needed, every bid is capable of being inferentially decoded and we merely need to trust partner to make a super accept over 5h with AQ.

 

If opener has let us down by failing to super-accept over 5h and somehow lacks the Qc AND has xxx or worse in clubs (almost certainly not possible), 7s is still by no means automatically sunk.

 

If the opponents make it a bit tougher:

 

1S [3D] 4NT [P]

6D [P] 6H/7S [P]

7S [All P]

 

4NT = BW or RKC. 5s may be down opposite AQxxx, xxx, AK, Jxx but I am not going to assume the worst. Partner is virtually guaranteed to have a H honor of some sort.

6D = if you are asking, I have plenty, plus a D void. Can we possibly make a grand?

6H = something about H's and I am trying for a grand -- note that this is an excess of caution because partner, again can have nothing in Ds and so must have all or nearly all of the missing cards.

7S = I am good in Hs.

 

Again, no exotic agreements needed. 6Ds in the only unusual bid here but almost every advanced player should be capable of finding it as a response, and working out what it means when it is made as a response.

 

Now . . . if either P or overcaller is prone to psyches. Oy.

[mycroft]

And if 3♦ gets 4 or 5♦, or 2NT gets 3♦ from West, and either of those gets 5♦ from East, do we still get there?

 

I don't know what the colours are, but a 1x4x zero-count at favourable or all-white is probably not being silent.

Over (2d) 3d (4d) opener has a rather easy 5d and again the inference that this is a void is rather easy to make. 5h has the same meaning as before (or shows a card and a slam try, either way) and when opener jumps to 6s responder can carry on to 7s.

 

Over (2d) 3d (5d) opener bids 5h = extras on the way to 5s at a minimum. Responder definitely has enough for 6c at this point (being capable of inferring on one loser max in d), followed by 6d by opener (does this show more? it should show zero losers in d at a minimum), 6h by responder. Now opener must sign off in 6s having shown everything he can and with neither A nor K in clubs and I am not sure that responder can as easily see the Qc in opener's hand here. The question arises: does 6d show a full 13 HCP opening in addition to the d void? Otherwise stated, is opener the sort to rebid the same values? (5h already showed more than min opening -- either a void (d) or at least 13-14 HCP -- does 6d show even more?)

 

Over (3d) 4N (5d) opener bids 6d as before and we likely get to 7s but R does have to assume that 6d shows at least a 14HCP opening bid (much more likely here than in the previous auction). Is that a safe assumption given a partner who voluntarily committed to the small slam? I just don't see opener doing anything other than answering the (4NT) question with xxx in clubs. So this voluntary move should show the Qc or a strong two-suiter in the majors.
