Ohh, and also, u just wrongsided the NT, because opener has AJT9xx ♣ unfortunately with a side Ace

That seems unlikely since East has ♣10.

Over 3♣(_X): _P = 10, 3♥ = 9, 3♠ (cue-bid)= 7.
Over 3♠: 4♥ = 10, 4♠ = 2. If 3♣ set ♥ as trumps, then 4♠ should show a control.

3♣ shows heart support. It doesn't set hearts as trumps. We should still be able to get to 4♠ and 3NT. This is much more important than having yet another way to make a slam try. East's hand type is acceptable for 3♣. It is just a tad too weak imo.

No, i said at the table that i shd have bid 3♥ instead of cue. Not because i have 2♥ though, but because i needed a better hand for it. This hand doesnt worth with the opener on my left.

I strongly disagree that cue can not be made w/o 3 cards support idea.

I agree that the cue can easily be the best bid on only a doubleton, especially when it is Hx. But the actual east hand is a little skimpy.

TEAM MATCH,IMPS.

2♣=Precision, 11-16 ♣s

3♣=cue, showing ♥ fit

Which bid is MOST unacceptable to you and why ?

Thanks

prefer pass with the east hand not 3c.....

pard can have less than this and bid 2h.

frankly I dont understand the rest of the bidding so 50/50 blame

[655321]

Completely agree with MFA.

Not sure why there are 2 posts in this thread saying the East hand is too weak to bid. Passing partner's vulnerable 2 level overcall with a decent 10 count including Kx in his suit would be very bad and you would expect to miss a lot of cold games.

[mcphee]

The 3C cue is a little pushy in my view, even 2H is a tad thin, yet understandable as the hand may be shut out if they were to pass over 2C. The 3C hand really faced a problem once partner o/c 2H and passing is (IMHO)just too ridiculous to consider. Some unappealing options for responder, 3D which most consider F is an over statement as it will surely have us reach game and we are not sure we want game. 2S possible but if partner were to raise you are uncomfortable. When the 3C bid was doubled the over caller seems to have lost touch with the rest of earth with this 3S bid. I suppose discussion of what passing the double would mean was unclear, I like to play passing expressed interest and 3H shows no interest at all. The 2H bidder was out to lunch when they opted to try 3S, what ever they were thinking, it requires some "adjustment".

It is still wrong sided Qxx in dummy vs Tx in hand, small ♣ lead (assuming the guy on lead didnt make inspired J lead) U have to guess while no guess needed from otherside. (original hand didnt matter, regardless we had no business in any game)


@Mcphee : our agreement is pass showing the weakest. Right or wrong, we believe pass gives cuebidder another chance to make a last attempt if in doubt still. (Rdbl-or by bidding the suit below the supported trump) We also dont play 3♥ over double any better than pass except an extra trump.

If our agreed suit was a minor, for example if pd overcalled 2♦ over 2♣, and cue was doubled, then the difference between pass and 3♦ is ♣ stopper both showing bad hand.

[whereagles]

I've yet to see what's wrong with 2NT over 2♥... Shape/strength should always come before stoppers, but maybe that's just me.

It's a style issue, you can overcall solid in 2nd seat and reopen aggressively in 4th seat or you can bid aggressively in 2nd seat and reopen with better hands.
I favor the later, but most important is to use the same style as your partner.

If the given West hand is a minimum, than West has no 3♠ or 5♥ bid.
If the given West hand is a maximum, than West has a slam try opposite partners 3♣ bid that should be much stronger.

[awm]

I think 3♠ is the worst call. South essentially let West off the hook by doubling 3♣, allowing an easy pass to show a hand with nothing much to say. Even without the double, the West hand is not really an accept of an invitational heart raise.

While the 3♣ call is not personally to my taste (I prefer to bid my suits rather than raise partner on doubleton), any choice by East is at least a mild distortion (in terms of either strength or support or stoppers). I don't think 3♣ is nearly as poor a call as 3♠.

The suggestions that West should have passed over 2♣ or that East should have passed partner's 2♥ overcall are somewhat ridiculous to me.

This is interesting since I feel the oppsite.
We do not know the vulnerability here. I myself have no particular high requirements for an overcall, but overcalling 2♥ with at best a mediocre 5 card suit, a balanced hand (weak notrump range) and Qxx in opener's six card suit (The ♣Q most likely being worthless on offense), is asking for trouble. You have at least a nine card fit with your RHO. Is it really difficult to see what will happen should LHO have a couple of points opposite a limited opener and a singleton ♣? Besides going for a number, there will be nothing on for them.
Meanwhile how good are your game chances when there are at best around 11-15 HCP to be shared between LHO and your partner? Sure, not zero. After all partner could have ♥ support, could have most of the outstanding points and could be short in ♣. But my guess is, chances, that all of this will happen, will be a single percentage figure and then partner may reopen. Going for a big number is at least 3 times more likely here against seasoned opponents.

Now let's look at advancer's hand. He has a doubleton in opponents suit, the worst holding you can have for game chances, in particular when ♣ were not raised and ♣Tx does not bode well for 3NT either.
I can understand 3♥, because game in ♥ could be on, if partner has an (unusual) good hand for his overcall.
But for my money I take the plus and pass, particularly non vulnerable. This hand will likely turn out to be disappointment in a high level contract. Too often you will go minus if you continue with this aceless semi balanced rubbish beyond the two level.

But cuebidding with this stuff at the 3 level without a known fit, is not just a tad too weak. This again is simply asking for trouble.

Of course overcaller should have passed over the silly double of 3♣, but I do not like my chances in any contract beyond 3♣.

Your post is very incosistent Rainer, if you have higher standards for LHO to overcall it is ridicoulous to also think abou pasing east's hand.

My standards are not higher, they are different. The West hand is a good example, how a direct overcall at the two level should not look like.
An overcall at the two level should show a reasonable six card suit, preferably with shortage in opener's suit.
From time to time I will overcall at the two level with a good 5 card suit, if I am unbalanced or short in opponents suit or if I have extra strength. But being balanced, having a mediocre 5 card suit and Qxx in opener's known long suit and being vulnerable, where is the point?
If West had the ♥ queen and the ♣ace instead of the ♣ queen and the ♥ ace, I might still refrain from overcalling but the hand would be substantially better.

With regard to East, it is a matter of judgement and you may disagree with me. The 2♣ opening has effectively preempted you. If the ♥ overcall had been at the one level you would be in a far more comfortable position.
You now have to decide what is the bigger risk: Pass and miss game or continue and turn a plus score into a minus.

From East's perspective, is West likely short in ♣, when you hold ♣Tx there and North did not raise ♣?
Give West a six card ♥ suit (and West may have overcalled on a 5 card suit) and a minimum opening bid, how likely is it, that you will miss a good game. Even if you do have an eight card fit, the fact that South has shown a long ♣ suit, makes it more likely that ♥s may be behind overcaller and not break well.
East is missing first round control in every suit and second round controls in two. The East hand would be better with the ♥queen and the ♠ king instead of the ♠ queen and the ♥ king.

I said I can understand a 3♥ bid by East. But to me the danger signs are clearly visible and Pass looks more prudent.
I am well aware that from time to time I will miss game. However, even vulnerable, where it is closer, letting it go at 2♥ will show a handsome profit in the long run .

Rainer, after i read this last reply, i am afraid i have to agree with Fluffy about inconsistency. Eventhough i agree with some of the stuff u wrote, You CAN NOT be so picky BOTH on the overcall and response side. It is imps and there is game bonus still, if they didn't change the rules recently.

I can sit and write long lecture about 2 level overcalls, that they can be upto a bad 17 hcp with 6 cards suit. And i can continue the lecture why it is right to start with an overcall instead of double in some hands. It is beyond my imagination to be so shy and passive in imps when u hold 10 hcp and Kx in pd's suit.

You wanna make the overcaller's hand a 6 cards ♥ ? Lets do it, lets even take out some hcps from him and add some shape. ATx AQ9xxx x xxx ATx AQxxxx xx xx . I have hell of a play in 4♥ after RHO opened vs that 10 hcp despite the fact that i gave pd a stiff on my KJxxx suit. And this overcall is not even close to some strong overcalls. What pass are u talking about ?

The modern 2♥ overcall is wide ranging and I do not doubt that game will be worthwhile if West is top of the range or very suitable for a high level contract. Trouble is, that this is less likely than West being at the low end for an overcall.

I decided to do a simulation, with fairly favorable assumptions about West (e.g. always more than 5 cards in ♥):

South: Precision club opener as described 11-16 HCP, either at least 6 cards in ♣ or 5 cards in ♣ and a 4 card major.
West: No 5 card ♠ suit, either 6 cards in ♥ and 10 to 17 HCP or 7 cards in ♥ and 10 to 15 HCP. But otherwise West could be very distributional.
North: Less than 4 cards in ♣ (no raise), no further restrictions

1000 random deals, double dummy results with West declarer in a ♥ contract:

4♥ (or more) would make on 295 deals or 29.5%
3♥ would make on 618 deals or 61.8%
2♥ would make on 884 deals or 88.4%

Your chances to make game is around 30%, but of course West will not always guess right when to accept the invitation, not least because some games depend on a favorable layout of the North South cards.
Meanwhile your chances to get a positive score drops from close to 90% to less than 60%, again because West will not always know when not to accept, not least because of an unfavorable layout of the North South cards.
If you assume that West will accept an invitation of 3♥ in half the cases (most players tend to accept more frequently), the best you can do in theory is

295 games bid and made
205 times you go down in game
500 times you stop in 3♥, of which
118 times 3♥ makes
382 times you will go down in 3♥

So bidding on would mean you bid 295 games but you will get a minus score 587 times instead of 116 times, that is 471 more minus scores and on the remaining 116 minus deals you go down more, which also means you are much more likely to get doubled. This is theory, the practical decision will likely be worse.
I guess bidding 3♥ looks okay, but even vulnerable, it does not look to me a favorite over Pass.
Pass by East is certainly not ridiculous. I still maintain it to be prudent.

-How many of them actually goes down without double dummy defense ? did u check each of them ?

-How do u know if we will stop in 3♥ with 500 of them, did u check 500 hands 1 by 1 and decided those hands would pass 3♥ or did programme do it for u by bean counts ?

-Did u make a restriction for hands, especially 10-11 hcps where ♥ suit doesnt worth to overcall at 2 level ? Since we have ♥ K, can pd have anything less than Qxxxxx in your deals ?

-Did u check what are the results for 3NT in some of those hands where pd can bid 3NT ?

-Did u check what happens to 4♠ when pd has 4♠ and an accepting hand ?

-What kind of hands is pd raising to 4, assuming my hand didn't cue but just raised to 3♥ ? You need to have a decent hand to bid 4 when pd only raises.

-Did u restrict, at least a very good portion of hand to only ♣ lead ?

And a raise here (instead of a cuebid or a game bash) says exactly that, it says 'partner, I am making a courtesy raise in case you are have a very good hand', it does not say 'partner, I expect you to accept this one frequently'.

Without addressing other aspects of your simulation, this unrealistic estimate of 50% is enough to make your results questionable. If you play with numbers and get an answer that passing with the East hand is acceptable, it is more likely that there are errors in your assumptions than it is that you have proved that the whole of modern bidding is wrong.

If you do a simulation, you have to make some assumptions. I can change any of them or refine them and repeat the simulation.
Tell me what you consider unrealistic. No big deal.
The assumption that a typical Bridge player would accept in about 50% seems realistic if not conservative to me.
Many accept, unless dead minimum for their previous call, that is in many more cases than 50%. In fact I myself belong to the invite heavy, accept often school
