georgi Posted August 17, 2014 Report Share Posted August 17, 2014 Thanks for reporting. Improved in v31 to prefer NT if partner's forced suit is minor for keeping more options with balanced hand. If partner's suit is major GIB has option to cuebid with not 4card fit, bid NT with none and raise to 3/4M based on shape and strength. So summarized, with displayed hand GIB would bid 2NT instead of 4♣. Quote Link to comment Share on other sites More sharing options...
