johnu Posted August 14, 2019 Report Share Posted August 14, 2019 Great bid by GIB :) Among other things, 2NT showed 2-5 hearts, 2-5 spades, 2-6 card diamond support, plus possible club stopper, and point count range. What an amazingly flexible and descriptive world class bid. Doubler just needs to bid a 3 card heart suit to get to an 8 card major suit fit. WTP? 1 Quote Link to comment Share on other sites More sharing options...
helene_t Posted August 14, 2019 Author Report Share Posted August 14, 2019 It surprises me a bit that it didn't run to 3♥ when I doubled. Anyway, the problem presumably it that the hand is too strong to bid 2♥ yet too weak for 3♥, but it does have the requirements for a 2NT bid. I am not sure why it can't bid 3♥. This is a general problem GIB has with tweener hands. I recall somebody posted a hand that was too strong to raise partner's 2NT to 5NT but too weak to bid 7NT so it passed. I believe that particular issue has been solved, but more generally, GIB will go out of its length to distort distribution in order to get the HCP count right to the fifth decimal.

Yet another example of keeping us off balance. Expect the unexpected. Quote Link to comment Share on other sites More sharing options...
Stephen Tu Posted September 11, 2019 Report Share Posted September 11, 2019 Another example on a weaker responder. So maybe it isn't a "tweener" problem but just totally out of order rules prioritizing 2nt.
