Hi all,

---

What would be the meaning of redouble from opener? Big balance? any kind of extras? maybe conventional?

Does opener rebid change from non competitive bidding with:?

2♥
3♥
2♣
3♣


Do theese responses remain the same if no double exists?

Thank you all

Kind Regards,
Paul_S

I would expect the double shows extra strength and defensive values rather than shapely. The archetypal hand would be 18-19 balanced that has some interest in penalising the opponents rather than inviting or bidding game, but it could be a bit weaker maybe with some 5422 shape (4 spades would be ideal here).

The other bids remain much the same, although 2C and 3C now should have real club length rather than possibly being 3-card suits. The most interesting question is what you use 2NT for, since any balanced invitational hand would just redouble. The answer to that is likely to depend on the partnership's general approach, but maybe some game-forcing hand that doesn't want to jump to the three-level. This could be some 5-4 hands (which would let 3C be 5-5) or 6-4 hands, allowing responder to show their own suit.

I would like to bid 2NT with a strong 0544 or 1543, then a 3m rebid will show a 5-card suit.
Also, a 2♠ rebid probably tends to show six hearts, with just 4-5 shape you would usually redouble.

With no extras or shape, pass is a good option here.
