Some problems from last night:

Scoring: IMP

---

They open 4♦ on your left and pd doubles,RHO passes, what do you bid and what is your plan of action?

Scoring: IMP

---

They open 2♥ on your left, pd doubles, RHO passes how many spades do you bid and why?

Scoring: IMP

---

RHO opens 3♠ pass pass and pd reopens with 4♣, what do you bid now? What do you think about 4♣?

Have fun!

1. 6D, pick a major suit slam. No room for science.
2. 4S, 3 is tempting but we should have 10 spades and I have gotten burned too many times being chicken in auctions like this.
3. 5C. 4C should be a good suit and hand when vulnerable.

1. 5♦. I intend to raise his 5major to slam or pass his 6♣. If we are off the 1st 2 ♦ tricks or if 2 rounds of ♦ promotes a trump loser, too bad.

2. 4♠. Shows my hand. Denies a good hand in terms of high card points, since I did not cue-bid and then bid ♠

I do not make takeout doubles when very short in the other major, so I know that partner (if he thinks like me) has some support.

3. 5♣. I have no real thoughts about 4♣, other than that 5♣ is likely but not assured of having a play.

[inquiry]

#1, Five diamonds pick a major is out, partner will take that for exclusion. 6D might get partner thinking not only pick a major, but that I have a void (not that he would bid grand, but if they bid 7D he might think I have a void)....so I bid 5NT, pick a slam

#2, where are the rest of the hearts? I have one, partner doubled, and RHO didn't try to raise the preempt. I suspect partner has a big balanced hand (too good for 2NT) with heart stoppers. Thus I will trott out an unexpected 3♠ thinking he will correct to 3NT. If partner turns out to ahve the expected monster hand, we might have slam, maybe even in clubs. Bidding 4!S there will be no way to find out. IF I am playing with a timid partner, I might bid 4!s anyway.... .

#3. I pass 4♣, and I think we might not make it.

OK, if ever there was a reason not to play 'exclusion' this is it.... since when has a cue bid - not even a jump cue bid - in an opponent's suit suddenly become Blackwood, in an auction where we are already at the 4-level and haven't yet decided what suit to play in, never mind whether it's a game or slam hand?

[FrancesHinden]

1. On the principle of 'strain before level' I suppose I will cue 5♦ (which must show a slam try even on that principle). I'm less convinced than other people that this is worth a slam force; and if partner bids 5M I shall pay serious attention to passing. Aside from the major issue of two potential diamond losers, something such as AJxx Kxx x AQxxx is a non-minimum take-out double with controls in every suit and slam is no bargain, particularly after the pre-empt.

Yes, I realise slam could easily be cold. That's why they pre-empt.
A simulation would only help matters if you defined partner's minimum hand.

The main argument that I can see in favour of driving slam is that if we do have 2 fast diamond losers we may not be making at the 5-level either (just think of how the play will go starting with 3 rounds of diamonds - we will need a very robust trump suit).

2. 4♠ I suppose. This should be a 'no-slam-interest' call, because one of an immediate 3S and 2NT-followed-by-3S should be forcing with spades (and of course all your partnerships know which is which). I expect 4S to go off some of the time, but as game is making opposite many minimum take-out doubles without the perfect shape, it's a bit pusillanimous not to bid it. I could be persuaded that an invitational spade bid is correct.

3. 5♣. I wouldn't pass. I am toying with 4NT instead, but it's a bit of a position and I'd be more tempted at matchpoints.

[cherdano]

On 1), I would really prefer to invite to slam, but I can't do that without guessing the strain. So I bid 5♦ like everyone else. Better go down in 6 of the right strain than in 5 of the wrong strain.

1. 5D but I don't think I can make 5D.
I will then double cross partner and pass him in 5M, but be happy if he bids 5N or higher.
I have 2 problems here:
a. I am not sure about strain
b. I am not sure about level
If I wanted to stop in 4M its a total guess which suit.
I have a slam INV hand. Against silent opps, I probably have a slam force but here I do not think I have a slam force if partner has only minimal values and we have only an 8 card fit, given the bad breaks. If I can find a 9 card fit, then we likely have slam.

2. 2S. When you have a distributional hand without lots of high cards, and the auction indicates that partner is going to bid again, give him room to bid again. If you bid 4S (or even 3S) partner might get you overboard playing you for values as oppossed to just spade length. Now if partner bids 2N next or 3D, or cue-bids you can bid 4S next. If he bids 3C, you can cue bid. If he bids 3N, you have to guess between 4 and 5S, I am a 4S bidder.

3. I am torn between 4N (natural) and 5C. I think 5C is safer, but if partner's suit is really strong I would rather be in 4N. All of this depends on my partner's style. With a partner who will gamble 3N on a suficiently strong hand and long minor, even with nothing resembling a stopper, 4C is much more limited. Personally, I usually beleive vul pre-empts, and don't bid 3N without a stopper over them, but some players do...

Two posters think that 5♦ is a slam force.
I don't. I think I am perfectly entitled to pass 5M from partner.
I am showing doubt about strain and at least slam invitational values.

Now, it's arguable that our hand is worth a slam force. That's a different discussion...

[pclayton]

1. I will try 5N and pull 6♣ to 6♥. We might be off 2 diamond tricks, but I it seems mean to tease pard with a 5♦ call and drop him in 5M.

If I start with 5♦ and raise 5M to 6M, it sounds like I'm conveying a ♦ control. Even though Frances' thread mentioned that cues in preempted auctions don't promise a control, the fact that I'm unilaterally carrying on to 6 after a 5♦ cue should promise diamond shortness.

2. 4♠. Playing Lebensohl, 3♠ is forcing (2N...3♣...3♠ shows the invitational hand). I think 4♠ shows this type of hand.

3. 5♣. Heck if I know. 5 may be down or we can make 6.

1) 5D followed by a raise.

2) 4S.

3) 5C.

1. 5N is dangerous since it makes it impossible to play 6♣. Furthermore, it runs the risk that partner will play you for longer ♥ than ♠. I do not agree that the sequence of 5♦ followed by a raise shows a ♦ control. Quite the contrary: I think that either 5N followed by 6♦ or 5♦ followed by 6♦ or (possibly) an immediate 6♦ show a control.... whether and when the control is first round is an interesting theoretical question.

This is an interesting area, in which I suspect few partnerships have any explicit agreements. We have a myriad of possibilities:

5♦ followed by 5N over 5 major

5♦ followed by 6♦ over anything

5N followed by 6♦ over the expected (but not inevitable) 6♣

an immediate 6♦ cue.

5♦ followed by a raise

It is clear that we should NOT use all of these slam sequences as promising a ♦ control. Here, we have a slam hand with no control... if you think that this is an over-bid, then add whatever modest additional strength you need: an extra small ♦ or a juicy major honour or whatever pleases you. It is clear that we CAN have a slam force that requires help in choosing a strain without our holding a ♦control, so we have to have a method of showing that hand.

As for 5N, in my view that is a dangerous bid, since it commits us to a major suit contract when 6♣ could be best.

AJx Kxx Ax AQJxx. 6N is best, and 6♠ is fine, but 6♥ is horrible while the mundane 6♣ works out okay.

Axx KQx x AQJxxx 6♣ is the only slam that is favoured to make.



2. I agree with 4♠, but caution that it is entirely playable to use the jump to 3♠ as invitational and the 2N- 3♠ as forcing: indeed the entire concept of lebensohl is amenable to considerable work: see Kokish's suggestions (not sure where to find them on the net, and my notes of his methods are buried deeply in my basement somewhere, so please don't ask me )

Let me try out some general principles on these, and see how I get on.

To me, 5NT sounds like "pick any suit, I have 3 of them" and 5D sounds like "I have two suits, bid your lowest one". But that's just an extension from the lower levels where cue or responsive double usually has exactly 2 places to play. So as the doubler, with a 5413 I would bid 6S over 5NT, but I would bid 5H over 5D in case partner has hearts and clubs.

- 5♦ followed by 5N over 5 major
sounds like GSF in the selected major (only because I always play 5NT as GSF once we've (in theory) found a fit, keeps my life simple)

- 5♦ followed by 6♦ over anything
Grand try in partner's suit, first round diamond control. Only way to make a general grand try, as a new suit over partner's suit would be natural (strain before level...)

- 5N followed by 6♦ over the expected (but not inevitable) 6♣
Trying to torture partner.
OK, diamond control, grand try, prepared to play in 6NT

- an immediate 6♦ cue.
Diamond void, big 2-suiter, probably the majors (but pulling 6H to 6S is a huge black 2-suiter and hence invites a raise).

- 5♦ followed by a raise
OK, we've found where to play

[luis]

I love this discussion, it's fantastic.

Let me add some questions to the ones already posted about hand #1.

What would a direct jump to 5♥ or 5♠ be ?

[FrancesHinden]

Natural, invitational, pretty certain about strain.
I've even had that auction (unlike most of the esoterica discussed above).

Please no one say asks for a diamond control! Just shows a hand too good for 4M and not good enough for 6M.

It asks for a ♦ control

Actually, having it ask for a ♦ control is not outlandish. It appears that at least some of us (Frances and I for sure) think that 5♦ invites partner to bid slam with the right hand. Surely the 'right hand' would include a ♦ control, but a ♦ control is a necessary but not sufficient reason to bid slam.

Thus we can construct stronger advancing hands on which the only serious question to be asked is 'do you have a ♦ control'?

Thus AJ10xxx Kx xx AJx

It is very difficult to see how to ask about a ♦ control if 5♠ does not send that message.

And if our suit is ♥, our options are even less attractive: at least with ♠ we could cue and hope for a chance to bid 5♠ over the probable 5♥ (altho I am not suggesting that as a sequence on this hand type... note Frances' reasonable suggestion that this sequence would show both black suits)

My own thoughts are with Justin and Frances: the jump in the major sets strain and invites slam. As a matter of logic, few doubling hands will accept without a ♦ control, thus all we lose on are the few hands in which we are 'sure' that we have 12 winners and we hold the equivalent of xx in ♦. Reserving the jump to ask for a ♦ control, and that alone, seems to be too infrequent a situation in comparison.

[whereagles]

1. Who the hell is LHO? If he can be relied upon having 8 diamonds, I might try 5♦. If not, I'll stick to 4♠ and hope to have guessed right.

2. Pard seems to have some sort of strong balanced hand. The priority is to hog the hand, so a 2NT Lebensohl must be the right bid Then we follow with some nr. of spades and chances are we get to play the hand

3. Who the heck pard thinks he is, bypassing 3NT just because "I didn't have a stopper, pard!!" Bah.. bid 5♣ and let HIM sort his way out of that. HA!
