Imagine your LHO opens 1, your partner doubles, next hand passes and:

A) you bid 1, LHO bids 2, pass, pass, you bid 3
B) you bid 2, LHO bids 2, pass, pass, you bid 2.

What does each sequence show about relative suit lengths, and which (if either) shows a stronger hand?

P.S. this conversation was sparked by the hand Qxxx QTx void KT8xxx. How would you respond to partner's double?

Spades then clubs shows 45

Clubs then spades is interesting. Maybe 46?

How about 3-5?
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

For the first auction, I don't mind 44+, although it's rather risky on 44 only. On the 2-level, I definitely it should be 4M4+m, not necessarily 5+. Maybe I should rethink this approach, given that I sometimes double on a doubleton in an unbid minor, but then I would nearly always have 4 cards in the unbid major, so I guess not.
... and I can prove it with my usual, flawless logic.

IMO, Assuming that jumps tend to show good or 5+ suits ...
  • (1) Double (Pass) 1; (2) Pass (Pass) 3 shows 4+ s and 4+ s. e.g. x x x x x x x x x A K x x
  • (1) Double (Pass) 2; (2) Pass (Pass) 2 shows 4+ s and 3+ s. e.g. Q x x x x x x x x A Q x x

Both bids show competitive values, typically 7-8 HCP. With 9-11 you might bid 1N even without a stop.

Strongly disagree that 3 shows 4+ and 4+ (as opposed to 44+). You should insist on spades if you have 5. Why go to the 3-level when you can play in a 5-3 on the 2 level? Or are you talking about 58?

Not sure why but no one has suggested 3c as the immediate response? 6 card suit and a void - great playing hand - if pard happens to now bid 3d showing good suit and good hand i have a pure 3S bid available. And pard should now know i have 9+ cards in the blacks with some values. pretty clear to me. daffydoc

With regular partners, our agreement would be that the X guaranteed 4 w/ 15 or less points as the TOX would never bid again.

W/ the void and a known fit, I value the hand at 10 TP and would bid TWO . either a 1 or 2 bid can be made w/ ZERO points as a bid is forced by the TOX, true?

If the TOX can bid again, you have game, if not, your actions have stressed the LHO's next bid.

At bridge, you have to look ahead. You have to assume opener might rebid 2♥. So if you respond 1♠, you will have to bid 3♣ at your second turn.
So i would bid 2♣ first, then rebid 2♠​, showing a near positive hand with longer clubs.

The situations are NOT truly comparable because, in each case, partner's 2H cue bid suggests support for the first suit you bid. (Suggests, not promises, since partner could have a very big hand with a long solid suit of his/her own and be looking for a heart stopper; when partner cue bids, he becomes the captain of the auction for the partnership.) Thus ...

... when you respond 1S, you are to proceed under the assumption that partner has spade support and make another descriptive bid to limit the nature of your hand. 2S would be the weakest bid you could make. Your decision to bid 3C is forward going, showing club values (and usually 4+ card length). It forces to 3S at least.

... when you respond 2C, you are to proceed under the assumption that partner has club support and make another descriptive bid to limit the nature of your hand. 3C would be the weakest bid you could make. 2S is forward going and natural (value and/or length showing), but it may not be quite as good a hand as when you bid 1S first and follow it with 3C simply because 2S is "on the way" to 3C, the level your p's 2H cue bid forced the partnership to reach. If partner has 4 card spade support, partner will often raise the 2S bid or bid 3D (natural and forcing, perhaps temporizing; it is not a long strong diamond suit since partner failed to bid 2D or 3D over 2C).

With the actual hand, I would bid 2C and follow with 2S. Partner's cue bid committed the partnership to the 3C level, so there is no danger partner will call Pass after 2S. And now ...

... if partner bids 2NT, I will raise to 3NT.
... if partner bids 3C, I have enough to bid 3H or 3NT (depending on how you play 3H).
... if partner bids 3D, I will bid 3NT (show the heart values).
... if partner bids 3H, I will bid 3NT (show the heart values).
... if partner bids 3S, I will bid 4C (forcing - sniffing for slam since I could have had a working King less for 2S).
... if partner bids 4S (rare), I will pass.

Partner did not cue 2. Opener rebid it.

For everyone's convenience, these are the two auctions:

This distortion of suit lengths that is popular on BBO is really somewhat disturbing - I have seen many people bid 5 card majors before 7 card minors and similar actions which do usually result in bad contracts. With a two card differential it is pretty clear to bid the longer suit first. daffydoc

One spade is a forced response and says four spades and 0+, so to follow with 3c isa nonsense, with no values hence 2c should have been first response then 2s over 2hts showing 5/4 and 6/8, 2c also shows 0+.until next bid but would deny 4s. In short on the hand given with seven pts 1s is wrong

If you were 4-4 wouldn't you just double on the second round?

I guess you mean that we'll find the 4-4 through a scrambling 2NT from partner? I haven't thought it through a lot. I'm always a bit confused about "DSIP": when P doesn't know what I hold, how can he DSI? I guess he'd (other than 2S on four cards or a suitable three) just pass with balanced crap, bid 3m with a 5-card suit, bid 2NT with 4-4 in the minors, something like that?

I meant more situations when we bid the second suit on the 2-level, which I guess is restricted to (except if responder passes a second suit):
1C-x-p-1M
2C-p-p-2D. :)

Yes, that, except that I don't think he should pass very often. With a 33(43) shape that merited a double of 1, he ought to have good enough spades to bid 2.

Yes, I agree that could easily be 4-4.

Yes, like really. Poster is worrying about suit lengths, when the real question should be how do I do something forward going for my first bid? 1 is a joke for first bid! The only negative to this hand is lack of aces.

One issue is that partner might pass opposite 3 but raise 1 to 2. I hear the scoffing already, but showing our major suit can get us to games that 3 misses. I have some (albeit somewhat disgusted) sympathy for a 2 bid though!

There's no distortion. Partner wants us to bid a major and that's our priority. In the actual case partner largely denies 4S by passing 2H so 3C is pretty safe. Reaching 5C isn't a huge priority here, but the rebid of the minor shows a longer suit by reference.

In other instances if we had a weaker hand we'd bury the spade suit if the opponents bid to 3H by our next opportunity.

But I'm troubled by your global remark about distorting suit lengths with 5-7. The only other case I can think of is skipping diamonds after a 1C opening to show a major.

3C is right on values but otherwise horrible. Partner will be passing 3C with vanilla 13 counts with 4s and that's terrible.
