jillybean Posted December 18, 2011 Report Share Posted December 18, 2011 2♣, planning to invite in NT but the director will be called when the opps discover you both have Q♥ Quote Link to comment Share on other sites More sharing options...
Mbodell Posted December 18, 2011 Report Share Posted December 18, 2011 3nt. South has 12 high cards and a decent 5 card minor suit. North opened the other minor and rebid nt. It is possible that you have a 9 card ♣ fit, but you are going to have right around 25 points or so, which makes club game or slam less likely than 3nt.

Zelandakh Posted December 19, 2011 Report Share Posted December 19, 2011 I don't get the 3NT bidders. If this hand is a GF opposite a minimum opening bid then we should have responded 2C. That the given response is 1S, we can assume the OP opens light enough that this is wrong. Hence our systemic NT invite seems clear. Quote Link to comment Share on other sites More sharing options...
Flameous Posted December 19, 2011 Report Share Posted December 19, 2011 I don't think it's that straight forward. We might not hold GF opposite some unbalanced minimum opening. (Ie. many hands with 6♦)But balanced hands we open might be sound enough, always 12 or so that we want to GF now.That said, I'd invite but with better spots I would start with 1♠ but bid 3NT now. 1 Quote Link to comment Share on other sites More sharing options...
Free Posted December 19, 2011 Report Share Posted December 19, 2011 What is a 1/2 system? Quote Link to comment Share on other sites More sharing options...
blackshoe Posted December 19, 2011 Report Share Posted December 19, 2011 It's where you respond at the one level over opening bids at the two level. Or it's a system in which you have only half the agreements you need. Kind of like the ones I play with my regular partners. B-) Quote Link to comment Share on other sites More sharing options...
