zhasbeen Posted February 9, 2019 Report Share Posted February 9, 2019 Yet another lesson on how to be a terrible partner, courtesy of GIB: http://tinyurl.com/y6ahsz7b I don't know about you guys, but pass was a no-brainer for me. I have a 4-3-3-3 20-pointer with mediocre spots. I got 21% for passing. Quote Link to comment Share on other sites More sharing options...
steve2005 Posted February 9, 2019 Report Share Posted February 9, 2019 Quantitative with a 6-card suit. Only a true point counter would pull this. 1 Quote Link to comment Share on other sites More sharing options...
pescetom Posted February 9, 2019 Report Share Posted February 9, 2019 If N bids 3♠, how is S supposed to reply in GIBberish?3NT obligatory relay waiting for suit, or 4♦ showing 4-card? Quote Link to comment Share on other sites More sharing options...
steve2005 Posted February 9, 2019 Report Share Posted February 9, 2019 3♠ is minor suit Stayman.I think this is a problem in hand evaluation which Gib doesn't do it just counts points.Hand evaluation says this hand good enough for 6 if not off 2 Aces so stuck with Gerber Quote Link to comment Share on other sites More sharing options...
zhasbeen Posted February 10, 2019 Author Report Share Posted February 10, 2019 This 4NT bid is in the critical error category--not just a minor misbid. Even with a square 12 GIB should skip the quantitative and just bid 6 (20-21 + 12 = 32-33). With the diamond suit as it is, it should be considering a grand.

I don't think a quantitative invite with 12 flat is unreasonable. If all declarers on BBO were to play like Meck or Bessis then lower the invite to 11, but I see no good reason to eliminate it - just don't make it with shapely hands.

helene_t Posted February 10, 2019 Report Share Posted February 10, 2019 GIB doesn't have a way to transfer to diamonds. I think Stayman followed by 4♦ is the normal way to bid this hand. But I am not sure if this helps yourself and partner more than it helps opps. Probably just let the sims decide whether 6♦ or 6NT is better and then bid it. OK, Gerber can do little harm, I suppose. Not for checking aces (partner is exceedingly unlikely to have zero aces) but to see if they can double 4♣. If so, you can then decide to bid 6♦ (or 5 if missing two aces).

I'm with the Gerber bidders all the way, and as you say, it costs nothing to find out about the off chance you could be missing 2 aces (and have the defense cash them both with one in each hand). I'm not letting GIB off on quantitative with this hand, however. Quote Link to comment Share on other sites More sharing options...
wbartley Posted February 21, 2019 Report Share Posted February 21, 2019 In case anyone is interested. With North holding the given cards and South holding a 20-21 balanced hand, 6N makes 97% of the time. This means that the odds of you being off two aces are so small as to possibly make asking for aces before bidding 6 worse than not asking, given that East might have a chance to double for the lead. Just a thought. Quote Link to comment Share on other sites More sharing options...
