Thanks!

Despite (1) and (2) your comments (3) and (4) are sound and valuable. Thanks!

After, 1♥-1♠-pass,i had to bid with ♠xx♥Kxx♦K10xx♣AKJxx. Playing transfer advances, with 2♣,2♦ not forcing after an first level intervention,2N Jordan, 2♥ limit raise with 3 card support, no forcing bid available.

You believe (apparently strongly) that a GF jump shift describes the hand better than a jump rebid. There are a variety of weak hands with some HCP in hearts not suitable for game. But since I think that 3♥after 3♦ is not a natural force (how to bid else weak major 5=4 hands), leaving responder without a forcing rebid, a jump shift (but only for the last reason) is perhaps a better (?) alternative.

I wouldn't say 3♦ is obvious at all; this seems too much of an underbid to me, so I'm with the 3♣ bidders. But from responder's perspective, if opener did bid 3♦, you still have a natural, forcing 3♥ response.

Thanks for the comments concerning the use of unbalanced Diamond, which is efficient in this case. Also any kind of strong club (precision, super precision, etc.) could be effective. But what about the natural 2over1. The obvious 3♦ jump rebid leaves Responder without a logical forcing response, driving him to a 3NT underbid. Is there a natural solution in the context of 2over1?.

Actually, bidding 2♣ with 3 clubs happens with regularity.

Thanks again. Good analysis showing the importance of 4SF. I used 4SF but with a diverse priority order (first stopper, second 3card support) and missed recently a spade slam. I try now the order you proposed. I think to remember, something similar is described in Hardy's 2over1 book. Don't know which is the originator.

Fine. I guess this is Hardy-staff. I will use it in the proposed order until some NT contract is missed :rolleyes: Thanks all for the comments.

Ok with 3♠. Now 2♦ ask for stopper, show stopper or asks for 3card support in♠

What means after the sequence 1-♥-1♠-2♣ a 3♠ bid in 2 over 1. How is a 4 color forcing 2 ♦ to interpret?

Sorry, Partner had 6♦ NV against V. My double was DSIP and I don't blame Partners decision going to the 5th level. The blind 4♠ bid with a 5card suit finding a strong 4card holding in partner could be bbo "specific". 1 down in 4 ♠ is bad score in MP if 3♣ are makeable but playing IMP I should perhaps pass, I agree (?). Glad that many of you would have bid 3♣ and thanks all for the comments.

Partners hand was: ♠Q8,♥Q98,♦KQT7632,QJ I bid 3C, slight overbid :angry:, LHO jumped to 4S, which I doubled. Final contract 5C doubled 3 down. 4S are cold on a heart finesse, despite this our score was -8 IMPS. Anyway, I feel uncomfortable to bid NT with this major holding. By the way, our side can make only 3 tricks in NT.

How to bid the following hand in 2over1: ♠87 ♥86 ♦J106 ♣AKT986 after a 1♦ opening bid by Partner and silent opponent. 2 ♣ is GF and 3♣ is invitational with 9 to 12 points (Hardy). I excluded the non forcing 1NT bid for obvious reasons.

Lets call A your definition of TWCB and B the bidding sequences described for weak 5-9 majors hands. I and many others call the union A U B as TWBC. You and many others prefer to exclude B and give them another name or let unnamed. Fine, but I would never dare to claim you have not understand TWCB. Anyway thanks for the reply.
