This topic is kind of an extension of Haoni5's bidding problem in http://forums.bridge...showtopic=29949

In short, what is 'expert standard' in the sequences

a] 2 - (2x) -
b] 2 - (3x) -
c] 2 - (dbl) -
d] 2 - (pass) - 2 - (2x) -

I'm sure someone told me once that in a], b] and c] (re)double shows a weaker hand than pass, but I'm not so sure of the merits of this.

Thanks.
Ant.

P.s.

If it matters, our general sturcture after 2 is
2 = semi positive or better
2 = double negative
2 = 8-10 bal or 14+ bal
2NT+ = transfers showing a semi-solid suit or better (opener completes to set suit)

I don't know.

Bridge World Standard is:

Quote

If two clubs is overcalled, responder’s double shows double-negative strength and a pass is forcing. Opener’s double of the overcall shows a balanced hand.

There is no agreement about responder’s actions after two clubs is doubled.

I play this, including "no explicit agreement after they double 2C". :rolleyes: Will follow up on that one.
