1eyedjack Posted March 6, 2015 Report Share Posted March 6, 2015 I agree with OP. This looks better than most flat 11 counts. Agree it is borderline. But either way, passing 1N would be better than signing out in 3C. Quote Link to comment Share on other sites More sharing options...

Clearly, 3C is the worst possible choice. I am fine with it passing 1NT, but at least 2NT would make some sense. Quote Link to comment Share on other sites More sharing options...
johnu Posted March 6, 2015 Report Share Posted March 6, 2015 3♣ on a 4=2=2=5 hand with king empty 5th of clubs? Really GIB? Quote Link to comment Share on other sites More sharing options...
georgi Posted March 30, 2015 Report Share Posted March 30, 2015 Included for polishing in v34. It has holes with that 5m4M shapes which are described as 6-11TP where the 11 could be also 11HCP with bad values in shortness. Quote Link to comment Share on other sites More sharing options...
Stephen Tu Posted March 31, 2015 Report Share Posted March 31, 2015 Please, please change definition to SIXm4M shapes. This should never be 5 cd m IMO. And 10-TP or something like that. Quote Link to comment Share on other sites More sharing options...

Stephen Tu Posted March 31, 2015 Report Share Posted March 31, 2015 Do you feel the same way if the minor is Diamonds, by the way? When partner opens clubs? Yes I feel the same. Although it wouldn't matter for GIB since it doesn't use the Walsh "bypass diamonds" treatment. But it would matter for humans who might have bypassed diamonds not knowing GIB doesn't. My real preference is for GIB not to play such "bar bids" at all, using them for natural forcing 5-5 or something like that. But if it does play them I'd rather they not bid it on 4-5s, which to me lands in far too many ridiculous 5-2 contracts at the 3 level when 7 tricks in NT is much easier. 1 Quote Link to comment Share on other sites More sharing options...
1eyedjack Posted March 31, 2015 Report Share Posted March 31, 2015 GIB will never open 1C on a doubleton. Maybe it should, but as it plays you will not end in a 5-2 fit (unless you have psyched as opener of course). But no, I meant after a 1D opener, which in theory can be on 3 but in practice much less likely, so a bar raise on a 5 card suit has a bit more going for it statistically. It may still be right to insist on 6. Quote Link to comment Share on other sites More sharing options...

It may still be right to insist on 6. The "bar bid" definition applies when you are bidding the *unbid* minor at the 3 level. Raising partner's original minor is a completely different animal, because you also have the option of simply bidding TWO of partner's minor. Because GIB plays "NMF" and not some two-way scheme, or 2♣ always checkback. So arguably if you just want to sign off, you can simply try to buy it lower. And 3m should be invitational (if going through NMF would be forcing). I don't really think it's best to have 2 different signoffs in partner's minor, and lose one of the forcing/inv raise meanings.
