How would these two be bid?

4D 4S p 5S p 6S

Is your West accepting an invitation, or just admitting to a diamond control? With such poor suits, I don't think I'd accept an invitation as West.

 

I usually think that a five-level raise after a preempt should be played as invitational as well as denying a control in the enemy suit. Maybe this one is different, though?

Obv I meant 5S as demanding a bid of slam with a diamond control. Your treatment seems fine/reasonable. To be honest I was considering breaking discipline with the west hand and passing anyways, which suggests that your suggested treatment is correct lol.

 

west has the kind of hand that my father passes a diamond control asking even when he has one.

 

Nice. It would not surprise me if this was the percentage action. This would be a symptom of the problem that partner has no way to invite slam while showing no diamond control (assuming you play 5S as demanding a slam bid opposite a control). Of course if 5S is a demand for slam opposite a diamond control, you have no way to invite without one, and an invitational hand is likely much more common of a hand type opposite such a wide range, going back to gnasher being right.

 

If 5C or 5H was a cuebid, that might help this situation. Or perhaps if 5D could be any slam try, and partner would last train with a reasonable hand and a diamond control, that would be a partial solution (partner would also last train or bid slam with a nice hand and no diamond control, this could get you into some trouble, but it would be a rare set of hands where both hands are very strong and have no diamond control, they'd probably need almost everything else, or AKQ opposite a void where there is major duplication or something).

 

I'm not really into optimizing for every auction though, and my general meta rule would be that 5x is natural, 5D shows a diamond control, and 5S says bid slam with a diamond control, but gnashers meta agreement that 5S is a slam try without a diamond control seems better. How often do you have a slam force opp a diamond control really? Except in this thread!

Another option would be to use 4NT as initiating cue-bidding, 5 as Keycard, and 5 as demanding slam with a diamond control. That doesn't work so well after a 4 opening.

I was wondering about that. In sequences where the overcaller has jumped to 4M, I think it's best to play new suits as cue-bids. I'm not sure whether the same would apply in this sequence, though.

 

The 4 bidder has a wide range of hands, and his trump suit can be pretty weak, so I can imagine that there are hands where a 5 signoff would work well, with advancer having short spades and lots of clubs. On the other hand, even if I had a 5 signoff available, I don't think I'd use it very often, because it would be rare to know that 5 would be a better contract.

Definitely. I would assume this is standard, partner has shown a strong 1 suiter basically, not like you're going to pull it. I guess 4S over 4H could be a cause of debate, but not 5 level bids.

 

On the other hand, even if I had a 5♣ signoff available, I don't think I'd use it very often, because it would be hard to know thta 5♣ would be a better contract.

 

Meh. You will never know, but presumably there will be hands where it's percentage to bid 5 clubs opposite the wide range of possible spade holdings partner can have. Sucks if he has 7 good ones himself but this is not that likely. Especially if the auction was (4H)-4S, but even over (4m)-4S. I would be bidding with as little as a reasonably good 7 card suit and a stiff spade, I wouldn't have to wait for an 8 bagger or 7 nearly solid or anything.

 

That said it could be that that is infrequent enough + sometimes it's wrong to be pulling anyways + you would gain a lot by having 5x be a cuebid all combining to make it better to not play it as natural, but I wouldn't guess that that is so.

I have posted about this auction before but it does seems to be another good spot for denial cues, that is to bid 5D without a diamond control and other bids show one. Thus with a slam try and a diamond control we can bid 5S, with serious slam interest and a diamond control we can ask for key cards (or just bid it). Without a diamond control we bid 5D; partner can bid 5S without a diamond control or 5H with a diamond control but not good enough to force to 6 or anything else with a diamond control and a better hand. So for this hand it would give an auction of (4D) - 4S - 5D; 5H - 6S where 5D is slam try or better asking about diamonds and 5H shows a diamond control but would decline a slam try.

 

I find that this reversal works well in a number of situations; in auctions where we are certain to have a control in their suit (typically grand tries) then the reversed cue shows 1 loser in the suit while bypassing the cue shows 0 losers. The point is that with a control in their suit we are usually better able to take control whereas without a control we will generally need to seek partner's opinion. Gnasher's idea of switching 4NT and 5D may be even better but it is hard to say without having tried it.
