GIB finds inexplicable pass Is GIB trying to field potential psyches now?

I don't need to say anything other than this.

I had something similar happen many years ago (GIB passed 2N with an even better hand)

How is this even possible?

Words fail me.

I had a similar experience at my club a few years ago with a pick-up partner, an elderly lady with hearing problems. I opened an Acol strong two bid - forcing - pulling the bidding card from the box. LHO passed, so did my partner, and RHO passed, too. Before the opening lead I gently suggested to my partner that the bid was forcing. "Sorry" she replied, "I didn't hear your bid."

I missed a slam, too.

It seems GIB doesn't have any bids for strong hands with one minor; 3 promises both minors.

With that shape and 16 HCP, it jumps to 7NT, and with 12 HCP, it bids 4NT. 5NT is undefined and the description of 6NT is 13+ HCP, but that must be one of the autogenerated level-based descriptions rather than a database definition - it seems they just forgot to program bids for the 13-15 point range into the bidding database.

GIB should have a default action, other than pass, when a hand with substantial values fails to satisfy any of its requirements for other bids. GIB has such a default in other contexts.
For example after 2 - Positive - Any - ??, when GIB doesn't know how to continue, it leaps majestically to 6NT. Not always the ideal solution :( But usually better than passing :)

Jumping to 6NT is World Class bidding by GIB.
