In my opinion Gib does not differentiate values offensive from defensive of the holding. I'm not saying that it is easy to programme but it seems to be not very difficult.

My link How GIB could not pass for 4♠x ??

With this hand GIB should take into accout that pd is either void or singleton in spades and most probably will go higher. For such option GIB has zero values for him, while has very good values against 4S. And it will occur the worst what can be in bridge: instead of a big gain it will be a big loss :angry:

IMPs, Red vs White. After the bidding: LHO Pard RHO GIB 1♠ 4♥ 4♠ Gib passed <_< with: KJT53 3 J42 T942
