Lovera Posted February 8, 2015 Report Share Posted February 8, 2015 For the first ,honestly, i am agree with you: there is a void in club that GIB (i think) considers, then however doesn't bid RKCB ? For the second post again there is a longness in spade and there cards in hearts, but now we have a 5-4-2-2 and with only an Ace two losers can be not covered (then Gib could be justified). I suggest, if you were on declaration, to procede with RKCB lacking(=with necessary attemption) Aces too that probably has your GIB partner can stop,eventually in negative case,bidding at five level (i have personally experimented this one), bye. 1 Quote Link to comment Share on other sites More sharing options...
1eyedjack Posted February 8, 2015 Report Share Posted February 8, 2015 there is a void in club that GIB (i think) considers, then however doesn't bid RKCB ?For which we should be grateful. RKCB with a void (unless exclusion) is not something that we should encourage GIB to do. Quote Link to comment Share on other sites More sharing options...
iandayre Posted February 8, 2015 Report Share Posted February 8, 2015 The problem I believe is that GIB is evaluating its hand as a minimum 2C opener, despite the playing strength. A 4D cue is certainly correct, followed of course by S showing the HA. Now N can bid 5C hoping for a cue of the DK. Or just jump to 6S if that is too much to ask. Gee, another time a 4D cue is right to show the A, below game. Quote Link to comment Share on other sites More sharing options...
georgi Posted February 13, 2015 Report Share Posted February 13, 2015 Added term for discussion if EKCB is possible to be applied for next version (v33) in terms of when to be used and constraints for it. Of course replies will be the easiest part. Maybe at least for some clear auctions like: 1M - 2x 3x - 5z 1M - 2x2M - 5z 1M - 2x2y/M - 3M4♠(if 1♥ opening)/5z 2♣ - 2♦2M - 3M4♠(if M=♥)/5z But will add more information when scenario is more clear about it.
