case in point and has done this often enough to be noticeable.

I imagine it's another example of GIB taking the opp's bids a bit too literally in terms of HCP promised, if west has 25 HCP, you can't have HQ, it has a triple heart stop and you have no entry, so it thinks it should just cash out. Definitely something that can be improved IMO but they have to go deeper in the guts of the program to fix this sort of thing than the bidding definitions they have been fixing, quite a bit harder to do.

Winning the ♠K on the first spade trick looks like a an error. It could be right if declarer had AQ tight with no entries to dummy and a 2nd spade trick was the only way to get 9 tricks. I don't think GIB rebids 3NT with a long running suit with a minimum point count for a 2♣ opener hoping to run 9 tricks.

Based on previous bugs that have been posted, this may be impossible to fix. The funny thing is that GIB upgrades all the time, sometimes by 3 or 4 HCP in other auctions, but it takes NT HCP ranges as sacred that can't be deviated from.
