Bbradley62 Posted May 15, 2011 Report Share Posted May 15, 2011 [hv=myhand=M-22059370-1305381241]360|270[/hv] I'm copying this hand from another thread. GIB doesn't seem to play UVU in the usual way. Quote Link to comment Share on other sites More sharing options...
BillHiggin Posted May 15, 2011 Report Share Posted May 15, 2011 I'll bite.What is "the usual way"? The explanation given for 3♣ seems to match what I think is the standard(original version). Danny Klienman suggested another approach which I would prefer if all other things were equal. But competing versions is always a very real danger.

Bbradley62 Posted May 15, 2011 Author Report Share Posted May 15, 2011 I think this explains the most common understanding of the convention, from http://web2.acbl.org/documentLibrary/play/Commonly_Used_Conventions/unusual.pdf' . There are different variations — this is one of them.1. Bid 3♣ with a limit raise or better in hearts.2. Bid 3♦ with a limit raise or better in spades.3. Raise partner’s major with 7-10 support points.4. Bid three of the other major with a hand similar to a good weak-two bid — this is natural and constructive but non-forcing.5. Double with a hand that is worth a redouble of a takeout double. This says that you can double at least one of their suits for penalty and promises another bid. Added later: The theme is to bid the lower of opponents' two suits to show the lower of the other two suits (one of which parter has already bid) and bid the higher of opps' two suits to show the higher of the other two.

gwnn Posted May 15, 2011 Report Share Posted May 15, 2011 I first learned it as 3♣=hearts3♦=spades but in Robson-Segal they give (I think)3♣=other major3♦=raise of partner's and GIB appears to play3♣=raise3♦=other major Quote Link to comment Share on other sites More sharing options...
Bbradley62 Posted May 15, 2011 Author Report Share Posted May 15, 2011 Thanks. Then, is it always lower=partner's suit and higher=other? Quote Link to comment Share on other sites More sharing options...
gwnn Posted May 15, 2011 Report Share Posted May 15, 2011 oh well I don't know if it works for minor suit openings as well. I've never heard of that frankly. Quote Link to comment Share on other sites More sharing options...
Bbradley62 Posted May 15, 2011 Author Report Share Posted May 15, 2011 ok, then what happens over 1m-(2NT)? Quote Link to comment Share on other sites More sharing options...
gwnn Posted May 15, 2011 Report Share Posted May 15, 2011 i dont know.. sorry. Quote Link to comment Share on other sites More sharing options...
BillHiggin Posted May 15, 2011 Report Share Posted May 15, 2011 ok, then what happens over 1m-(2NT)? Older version (GIB): cheap cue = raise, dear cue = 4th suit Kleinman version: cheap = cheap, dear = dear. Exception for non touching suits - transfer.

Bbradley62 Posted December 12, 2011 Author Report Share Posted December 12, 2011 GIB's handling of UVU might be good info to be added to GIB's System Notes. Quote Link to comment Share on other sites More sharing options...
georgi Posted December 12, 2011 Report Share Posted December 12, 2011 ok, then what happens over 1m-(2NT)? For GIB when there are two suits shown ( clearly ) it could use these two suits by showing support in partner's suit and unbidded 4th suit. This includes 1♣ - 2♣ (majors) - ?=> 2♥ - Limit raise or better in ♣ -- 4+ ♣; 10-12 total points=> 2♠ - Constructive, 4th suit -- 5+ ♦; 10+ total pointsSimilar for 1♦ - 2♦ 1♥ - 2NT ( minors ) - ?=> 3♣ - Limit raise or better in ♥ -- 4+ ♥; 10-12 total points=> 3♦ - Constructive, 4th suit -- 5+ ♠; 10+ total pointsSimilar for 1♠ - 2NT 1♣ - 2NT ( ♦ + ♥ ) - ?=> 3♦ - Limit raise or better in C -- 4+ ♣; 10-12 total points=> 3♥ - Constructive, 4th suit -- 5+ ♠; 10+ total pointsSimilar for 1♦ - 2NT ( ♣ + ♥ ) Quote Link to comment Share on other sites More sharing options...
Bbradley62 Posted December 12, 2011 Author Report Share Posted December 12, 2011 For GIB when there are two suits shown ( clearly ) it could use these two suits by showing support in partner's suit and unbidded 4th suit..."could"? Does that mean you are suggesting a potential change for GIB's system, or are you telling us what GIB's system actually is? Please note that the OP was about an auction that started 1♠-2N, which is less obvious than 1♥-2N. Sorry, but OP was before I knew that myhands links eventually expired.

Please note that the OP was about an auction that started 1♠-2N, which is less obvious than 1♥-2N. Sorry, but OP was before I knew that myhands links eventually expired. I mean this is the actual possession in GIB book. GIB uses these sequences currently. 1♠ - 2NT - 3♣/3♦ is identical with 1♥ - 2NT, just 3♣ will show fit in spades and 3♦ will show constructive hearts. 1♠ - 2NT - 3♥ - Natural, not forcing -- 2- ♠; twice rebiddable ♥; 7-9 total points Quote Link to comment Share on other sites More sharing options...
Bbradley62 Posted December 12, 2011 Author Report Share Posted December 12, 2011 Thank you. I'd like to repeat my request that this be added to the GIB System Notes document, since interpretation of this convention is not universal. Quote Link to comment Share on other sites More sharing options...
barmar Posted December 12, 2011 Report Share Posted December 12, 2011 GIB always plays Lower = Limit Raise, Higher = Constructive, 4th Suit. While it's not specified in the system notes (I'll try to remember to update it the next time I'm working on them), the mouseover makes it clear.

Of course, you don't always get the benefit of the mouseover, such as when you're playing with (or against) a GIB in an Express game.
