Suppose the bidding begins (3)-4-(Pass)

Suppose that 4 shows clubs and says nothing about anything else.

Suppose you have some spades.


Partner probably won't have four spades but he might well have three. Or none. It seems that a call of 4 could help sort this out, using it to ask for three spades. With that meaning available, bidding 4 directly can show a hand that needs less support (even if I wouldn't be delighted with a void). With a little work this could be adapted to (3)-4-(Pass) as well.

I imagine I am not the first to think along these lines. Does anyone play it? I recognize that it gives up on 4 as a slam try in clubs but I think sorting out the games might be more useful.

I was discussing (3)-4 with Helene, who mentioned she sometimes played it as showing clubs and spades. I don't think I like that (comments welcome) but it got me to thinking about problems that I have had with the sequence (3)-4 .

If (3[HE)-4-(p)-4[he] is spade interest, how do you show a good club raise?

As I say, it could be a problem for a slam try. It's not impossible to develop some ways, but for the most part I think you give up on slam tries to improve the finding of games this way

I prefer to play all such cue-bids as looking for the best game.

I definitely prefer to play 4 as 5-5 clubs and spades. Many/most disagree. I think it's an important hand to be able to show, relatively frequent, and that almost all the time if you hold clubs any of P/X/3NT/5 is either your best bid or will suffice.

Brink/Drijver and also Cherdanno/Han play similar things when opps preempt over their minor suit openings so they probably also play it here, unless they discovered that it sucks.

We do? I believe you but I have no recollection of such a thing.
and the result can be plotted on a graph.

Transfer advances (as whereagles suggested) are a big help. Use 4 as a spade transfer.....you have to agree on when overcaller accepts...my suggestion is that he accepts with 2 or 3, otherwise bids something else....usually 5 but 4N is permitted to show secondary diamonds (you will very rarely have a hand that can keycard given that advancer's hand is largely undefined and hands that want to bid a natural 4N will almost always have chosen 3N over 3).

You can decide, if you choose, to use 4 as a transfer to hearts, thus a strong club raise, and 4 as a transfer to diamonds or, in better keeping with most transfer advance schemes, start the transfers at the cuebid, leaving 4 as natural and 4 becoming the strong club raise.

While I like (and sometimes play) transfer advances in this auction, I don't think it really solves the problem in the original post.

The issue was that you want to have a way to say "I have some spades, but prefer to play 5 if you have a singleton or void in spades" as well as a way to say "I have lots of spades, let's play in spades no matter what." The critical thing is being able to stop in 4 with both hand types when it's right. Transfer advances don't help since 4 is presumably a strong club raise; basically you need two different 4 bids to fix this problem.

Of course, that's assuming you consider the problem significant; I don't feel like occasionally playing 5 when we have a 5-2 spade fit (or playing 4 in a 6-1 fit instead of 5 in a better fit) is a huge issue.

How about two-step transfers? That is:

4 = spades. Then 4 shows doubt about strain.
4 = good club raise.
4 = diamonds. Then 4NT shows doubt about strain.

I'd never agree to such an obscure and specific piece of system, but it does solve most of the problems.

;) Agree that is a great idea, and agree that it should be appreciated rather than adopted.

I would say that it is not rare for me to have five spades when partner comes in with 4, Not everyday, but not rare either. After a preempt there of course will be some guess work. If I have clubs and good values for slam, sure I can just bid 6 on the thinking that if we get to a makable slam over a 3 preempt then that qualifies as a reasonable day's work. But other times I would say the situation is more like: Well, I don't really know if 5 will make or not, I suppose I more or less must bid it with any excuse, but it sure would be nice to stop in a ten trick game if one is available. It's in this situation that I want my two ways to bid spades.

Good or bad, it does not seem like a totally crazy convention and I assume someone has tried it. Otherwise I apply for copyright protection ;) .

I don't really mean to dis either the 5-5 treatment or transfers, but I am not convinced. Open to thinking on it, but not convinced. I think I get dealt hands with good values and six clubs more often than I get five-five. Bidding 4 rather than 5 allows partner to explore at least somewhat for a spade contract.

gnasher put up his response while I was typing this. I agree that the two step is a little complex, a related problem is that it works only after a 4 bid and not 4. For something that doesn't happen everyday, I want the same agreements to apply whether the minor is clubs or diamonds. Too much memory work for too little if it applies only to clubs.

But how many of the good hands with 6 clubs just bid 3NT anyway? Or double in case partner can pass or bid 3NT? Most, I would say.

Perhaps so. After the 3H preempt, I suppose it could go: X-3S-4C-4H when fourth hand has spades of decent but not great length and 3S-4C-4S with a hand that doesn't need much help in spades. One problem with this is that after X-3S-4C I don't think partner can pass like he could over a direct 4C. A more important problem though is that after the double, if 3H is raised to 4H and partner bids 4S, I will be very nervous if I don't have the spade length that he is expecting. On the other hand, after 4C-(4H)-4S I will be more comfortable since I promised values, but he is promising the spades.

I'm working on this and I appreciate the comments. My predilections here and elsewhere, are: Natural bids unless I am convinced some device is better. Here this translates as starting with a natural 4C and then using a device to find a spade fit if we can.

Thanks,
k

PS I am still wondering if anyone has played with the agreement I suggest. An early reply frm gnasher supports the general concept being it, using a cue to find the best game rather tahn as a slam try (or, if I may read a little into it, the first interpretation of the cue is a search for the best game, maybe later action shows otherwise) but this will only work if the pair has some agreements about how the search is conducted.

Seems like Zia/Rosenberg played something like this.

From Zia-Rosenberg CC notes:


(NOTE 44) CHOICE OF GAMES CUEBID: THIS OCCURS USUALLY AT THE FOUR LEVEL AND USUALLY AFTER OPPONENTS HAVE MADE A PREEMPTIVE BID OR RAISE. THEY DO NOT APPLY IF 4-LEVEL CUE BID IS ONE UNDER LAST SUIT WE BID. E.G. AFTER (3) 3-(P) 4, OVERCALLER SHOULD ROUTINELY BID 4 WITH 5-3 IN THE MAJORS, EVEN 6-3 WITH BAD . REPEAT CUE OR JUMP PREFERENCE BY ADVANCER SHOWS SLAM TRY WITH CONTROL. (2) 2-(P) 3 SUGGESTS FEWER THAN 3-CARD , UNLESS REPEAT CUE. RETURNING TO THE HIGHER RANKING OF TWO REMAINING PLACES TO PLAY IS A SLAM TRY. RETURNING TO PARTNER'S SUIT AFTER COG CUEBID IS A SLAM TRY.

CoG (Choice of Games) cue bid is our style. We focus on finding the right game, prepared to take a hit on slams.

Had this the other day:

(3)  3  (no)  ?

65 AQ762  74  KJ85

Partner bid 4 over my 4 with JT4 which proved best.

Transfer advances not so useful with this example.
Not keen on non-leaping Michaels either. Was playing it the other day & held something like

AKxx  xx  x  KQTxxx

Over 3 I tried 4 anyway (5-5 blacks) but our 6-3 club fit proved better than the actual 4-3 spade fit we played.
I would l ike to bid 4 natural, depending on partner to bid 4 to check for a spade fit.

Shevek and Ron,

Thanks, guys. Whether it's good or bad and whether we play it or don't, I was having great difficulty believing that this approach had never been tried. Hell, if Zia and MR play it, perhaps it even has merit.

Thanks again
