Does whether partner would bid 1 or 2 with a 3343 have any relevance here ?

This hand was presented in a bidding contest and all you know is that vanilla 2/1 is the imposed system. Presented by Richard Pavlicek a long time ago, but in the BB it was bid by Bobby Levin.

Absolutely. I don't want partner to play in a 3-3 fit. I suppose I could correct to 3c but I'm not that strong.
I pass. I don't think a second double leads to anything good.

It may depend on the system, e.g. on how I show approximately this many hcp and a balanced hand, whether 2 promises 5+ D and whether we play Good/Bad.

I think this is an easy double no matter which system, form of scoring, state of the match or psychedelic influences I might be under.
We have an A and a Q more than we promised. Game is easily possible.

Bobby Levin in the 1981 Bermuda Bowl bid 3D, yet they still missed 3NT when his partner had Qxxxxx in diamonds and A10x in hearts.

I like Levin’s bid because it gives partner more information while showing similar strength as double.

Vanilla 2/1 in the bidding contest.

the worst that may happen if we X again is that we end in 3 and go for -2. the chance of that being 3X-2 is less than 5% imo. east is weak weak. if west is trap passing with a good hand and north has nothing then I still think they will bid 3 here other than X 3 bid by us. south is in balance seat with extra values: X again is only way to show this. passing may be best as helene_t indicates if partner is terrible 3343 shape, but 3352 shape is 15.5% and 3343 is 10.5% so I take chance here.

The basis of this bidding contest was to gauge judgment. With an Ace more than advertised, pass seems awfully conservative.

How likely is it that partner will convert the second double to penalty? Not very at imps . So why not bid 3D instead of forcing your partner to bid 3D?

Maybe partner would like to bid something other than 3D? Either way a voluntary raise to the 3-level typically shows 4-card support, double paints a more accurate picture of our cards even if the final contract may well end up the same.

... and Good/Bad not available in response to my double I'm going to bid 2N (16-18 BAL-ish?) now.

Yes, a voluntary raise normally shows 4 - else this would not have been a bidding problem. Posted Image It really gets down to 2 questions: should this hand bid again? If so, is 3D or double better?

Here is what Richard Pavlicek said as moderator:



Quote

Keep it simple, and I agree. The consensus to raise partner's suit is the practical way to show extra values. The lack of a fourth trump is a concern, but the enemy raise increases the chance that partner has 5+ cards. Further, A-K-9 is strong enough for Moysian appeal. If partner has some disgusting hand like x-x-x, x-x-x, J-x-x-x, x-x-x, it's just too bad.

A second double seems like the normal approach, conveying the strength about right; but partner will expect four spades. Hence, his most likely action will be to bid a three-card spade suit, which will solve nothing. If you then correct to 3D , he will expect you to have even greater strength.




PS: In the original poll, I doubled with this hand and so did Justin Lall, so I felt I was in great company. I miss Justin.

2N would be considered by most I think to be 18-19. Seems an overbid to me.

Nige, you may be interested that Richard Pavlichek reversed your scoring, awarding 3D the top score and double the second highest. Voting was 3D: 546 votes Score 10, Double 362 votes Score 8, Pass 288 votes, Score 6, 3C 139 votes, Score 5

1x-P-P-2N most people play as something like that, x then 1N is a second seat 1N overcall because the 4th seat one is 11-14

I forgot this was originally a pass out seat double and was thinking it was direct seat. Duh
