Stefan_O Posted January 7, 2018 Report Share Posted January 7, 2018 Playing w gib, I held K2 AT643 Q3 AT94 Partner opened first hand 1♣, and the bidding started: 1♣ (1♦) 1♥ (P)1♠ (2♦) ?What to bid here?With a human pd, I would most likely bid 3♦ to ask for ♦stopper or secondary ♥support. But 3♦ was described as 4-card ♠support, which makes this hand virtually impossible to bid sensibly.Other options were:2NT = nat invite.3♣ = 4+ ♥, 4+ ♣, 9+ total points ///// (non-forcing, right?)3♥ = forcing with 6+♥ Quote Link to comment Share on other sites More sharing options...

A double of 2D should find you 3 card H support, partner showing long clubs, bidding 2N or even passing with a suitable hand. Quote Link to comment Share on other sites More sharing options...
smerriman Posted January 7, 2018 Report Share Posted January 7, 2018 Are you sure you have the auction right? At a practice table, GIB is saying 3♣ at that point shows 4+ ♥, 4+ ♣, 9+ total points, which seems to describe your hand. (Though I agree GIB assumes a cue bid shows support far too often).

Forgot to mention, X was defined as "biddable diamonds" or something equiv, so too dangerous playing with Gib. Quote Link to comment Share on other sites More sharing options...

Yes, bidding is correct, and your description probably right -- my bad, typing from memory, sorry :(But my experience (from all earlier robot-games) anyways means it's non-forcing, which seems risky with my 13hcp. I noticed now, at another table, someone else actually opted for a death-defying 3D (showing 4sp!) and robot-North then responded 3NT!So I would suspect it is just an erroneous description, then.Gib really does NOT interpret 3D as 4+spades....

This is so weird... at yet another table someone opted for the 3C over 2D. Robot-North then responds 3S! So if I show spade-support, it bids 3NT.While if I show club-support, it rebids spades... :blink: [hv=http://www.bridgebase.com/tools/handviewer.html?bbo=y&lin=pn%7CSouth%2CRobot%2CRobot%2CRobot%7Cst%7C%7Cmd%7C3SK2HAT643DQ3CAT94%2CS87653H85D97CK632%2CSQT94HK7DA85CQJ75%2CSAJHQJ92DKJT642C8%7Csv%7CN%7Cah%7CBoard%205%7Cmb%7C1C%7Can%7CMinor%20suit%20opening%20--%203%2B%20%21C%3B%2011-21%20HCP%3B%2012-22%20total%20points%7Cmb%7C1D%7Can%7COne-level%20overcall%20--%205%2B%20%21D%3B%208-17%20HCP%3B%209-19%20total%20points%7Cmb%7C1H%7Can%7CFree%20bid%20--%204%2B%20%21H%3B%206%2B%20total%20points%3B%20forcing%7Cmb%7CP%7Cmb%7C1S%7Can%7C3%2B%20%21C%3B%203-%20%21H%3B%204%2B%20%21S%3B%2011%2B%20HCP%3B%2012-18%20total%20points%7Cmb%7C2D%7Can%7C6%2B%20%21D%3B%2017-%20HCP%3B%2012-19%20total%20points%7Cmb%7C3C%7Can%7C4%2B%20%21C%3B%204%2B%20%21H%3B%209%2B%20total%20points%7Cmb%7CP%7Cmb%7C3S%7Can%7C4%20%21C%3B%203-%20%21H%3B%20rebiddable%20%21S%3B%2014-15%20total%20points%7Cmb%7CP%7Cmb%7C4C%7Can%7C4%2B%20%21C%3B%204%2B%20%21H%3B%209-15%20total%20points%7Cmb%7CP%7Cmb%7CP%7Cmb%7CP%7Cpc%7CHQ%7Cpc%7CHA%7Cpc%7CH8%7Cpc%7CH7%7Cpc%7CCA%7Cpc%7CC3%7Cpc%7CC5%7Cpc%7CC8%7Cpc%7CC9%7Cpc%7CCK%7Cpc%7CCJ%7Cpc%7CD4%7Cpc%7CD9%7Cpc%7CD5%7Cpc%7CDK%7Cpc%7CD3%7Cpc%7CH2%7Cpc%7CH3%7Cpc%7CH5%7Cpc%7CHK%7Cpc%7CD8%7Cpc%7CD6%7Cpc%7CDQ%7Cpc%7CD7%7Cpc%7CSK%7Cpc%7CS3%7Cpc%7CS4%7Cpc%7CSA%7Cpc%7CHJ%7Cpc%7CH4%7Cpc%7CS8%7Cpc%7CC7%7Cpc%7CDA%7Cpc%7CDJ%7Cpc%7CH6%7Cpc%7CC2%7Cpc%7CS6%7Cpc%7CSQ%7Cpc%7CSJ%7Cpc%7CS2%7Cpc%7CS9%7Cpc%7CDT%7Cpc%7CHT%7Cpc%7CS7%7Cpc%7CCQ%7Cpc%7CD2%7Cpc%7CC4%7Cpc%7CC6%7Cpc%7CST%7Cpc%7CH9%7Cpc%7CCT%7Cpc%7CS5%7C]600|450[/hv] Quote Link to comment Share on other sites More sharing options...
jdonn Posted January 7, 2018 Report Share Posted January 7, 2018 GIB has a general rule that cuebids of the opponent suit in otherwise undefined auctions show support for partner's last bid suit. Here I would double, playing with or without GIB. It says biddable diamonds, but he probably won't pass, and if he does I think there is a good chance that is best if you have no major suit fit.

Hi jdonn,But why does Gib bid 3NT over 3D above, if it really shows 4sp support? Quote Link to comment Share on other sites More sharing options...
jdonn Posted January 18, 2018 Report Share Posted January 18, 2018 Hi jdonn,But why does Gib bid 3NT over 3D above, if it really shows 4sp support?GIB simply thought it was best. You could always pull if you had four spades anyway. Quote Link to comment Share on other sites More sharing options...
