lycier Posted December 17, 2015 Report Share Posted December 17, 2015 I really appreciate all the replies!The actual situation was probably beyond any reasonable solution by normal agreements (i.e. does opener have the right major suit queen?). Actual hands (true spot cards this time):[hv=pc=n&s=sq93hj86da93cakqt&n=sakhat2dkqt876c92]133|200[/hv] [hv=pc=n&s=sq93hj86da93cakqt&n=sakhat2dkqt876c92&d=s&v=b&b=7&a=1n(15-17hcp)p2n(transfer%20to%203D)p3c(good%20support)p3h(cuebid%20with%20stopper)p3n(partial%20stopper%20in%20S%20at%20least)p4s(first%20round%20control)p5c(first%20round%20control)p5s(second%20round%20control)p6c(second%20round%20control%2Cinvite%20to%207)p7d(Very%20good)pp(Good%20luck%2Cpartner!)p]400|300[/hv] You said " i.e. does opener have the right major suit queen? "Yes, let's make some analysis.After 3♣ , 3♥=cuebid up-the-line,responder has not promised any stopper in ♠,opener should rebid 3nt to show a stopper in ♠,then responder should know opener has ♠Q !After 6♣ invitation,7♦ is a reasonable judgment.

Left2Right Posted December 17, 2015 Report Share Posted December 17, 2015 Bill: You are not alone. A couple of years ago I wrote via e-mail to a lady player of international repute (one of those with a BBO star by her name) asking how she and her best partner, another star-boaster, would approach exactly this challenge. To my great surprise, she replied that the two of them had not even discussed it, let alone reached an agreement. (They have now.) In honor of this common problem, I have added yet one more BBO constraint file to my public stash so you can test whichever method you have in mind. You'll find it at http://www.charlesandgerry.com/bridge/constraints.html (SCROLL DOWN on the page.) 1 Quote Link to comment Share on other sites More sharing options...
PhantomSac Posted December 19, 2015 Report Share Posted December 19, 2015 If you are able to keycard via 4D or 4H and your partner shows 2 keycards your next bid should be to show the SK rather than ask for kings. Then you will have shown your whole hand minus what your 3 card suit is (which admittedly can sometimes be an issue). LOL example and all but QJxxx of spades and the minor suit aces = a grand. On the other hand partner can have both of the other kings and we still need a trick. Knowing how many kings partner has is not what we need to know, he will be much better placed if he knows we have 6 diamonds to the KQ, the HA, and the SAK. Example auction: 4H RKC, 2 5C w/o, 5S I have the SK. Quote Link to comment Share on other sites More sharing options...
lycier Posted December 19, 2015 Report Share Posted December 19, 2015 Whatever it is minorwood or redwood,both don't resolve controls clearly in the side suits at the same time since this is not a simple problem on RKCB.If it is playable for what you said,you are difficult to find 7♦/7nt.
