helene_t Posted December 7, 2018 Report Share Posted December 7, 2018 http://tinyurl.com/yb4dd2tj Hearts is trumps and they double our 5♦ response which shows one keycard. One KC is enough but we need a diamond control. Our options are:pass: 2nd round controlrdbl: 1st round control5♥: sign off, which could be either a KC short, or a missing diamond control, or both Partner had a diamond control so we miss a cold slam. What about:pass: we have enough KCs but no diamond control Quote Link to comment Share on other sites More sharing options...
The_Badger Posted December 7, 2018 Report Share Posted December 7, 2018 Your suggestion is an alternative, Helene, but I think the big problem here is that North hasn't (I assume) got the option to splinter after your 2♠ bid. Don't think you'll miss the slam if that happens, however... ...East then proceeds to find the extraordinary lead of a small ♦ :) Quote Link to comment Share on other sites More sharing options...
helene_t Posted December 7, 2018 Author Report Share Posted December 7, 2018 Just a thought: pass: denies diamond control. Partner can redouble to ask for the queenrdbl: shows diamond control, asks for the queen5♥: not enough keycards Quote Link to comment Share on other sites More sharing options...
johnu Posted December 7, 2018 Report Share Posted December 7, 2018 How do you know what GIB thinks pass shows? Usually pass has no description? Does this auction show a description for pass? Quote Link to comment Share on other sites More sharing options...
smerriman Posted December 7, 2018 Report Share Posted December 7, 2018 How do you know what GIB thinks pass shows? Usually pass has no description? Does this auction show a description for pass?You can always see a definition of your own passes when deciding what to bid. Just not what passes mean by other players. But Helene, surely if you don't have a diamond control, you cue 4♠ rather than 4NT. I know that doesn't normally work well with robots who don't understand cuebidding, but I would say that would be the thing worth fixing, vs trying to allow you to recover when the opponents help out with a double.

But since "pass" now denies a diamond control, apparently the GIB system does not require me to wait with blackwooding until I have verified all controls. Given that I am now in a situation where I could have enough keycards but missing a diamond control, I think the system should allow me to bid such a hand somehow.

So 5♥ is a normal signoff, while your other options assume you didn't have two quick losers to start with. 1 Quote Link to comment Share on other sites More sharing options...

My problem was that pass and rdbl both promised a diamond control so I could only sign off. Or bid slam, I suppose, just gambling that partner has a diamond control.

Partner signs off with no diamond control, redoubles with diamond control and no queen, other bids = diamond control, queen, and showing feature as in normal queen-ask reply Anyway, surely GIB-East would have found the diamond underlead against 6♥?
