Help
Not surprisingly, this was a bottom.
Just why did my costly and AI enhanced GIBBO stop in 6♥ here ?
I cannot see how a simulation or any reasonable algorithm could suggest that a trick might be lost in 7NT, given the information received during the auction.
I can imagine that GiB is rigidly locked into playing in hearts and cannot see the NT alternative like a bridge player would. But even then any reasonable number of simulations should get it over fear of the grand.
Maybe I am missing something.

I was thinking about how dumb the bot was and I came up with a plausible (barely) solution. The bot started out by assuming your 0-3 showed 3 and proceeded to queen ask. Your 5n
was correct opposite any sane partner but the bot is ummm not always that. It seems possible that it read the 5n as a warning you had the Q and zero keys and a 6h bid (in its "mind" would have said no kings and verified 3 keys.

The straightforward answer, as usual, Pescetom, is that the GIBBO robots are hopelessly incompetent at bridge. The hand you provided is perfect evidence.

Yes I guess that is possible. Or perhaps more plausible, that it plays 5NT as all three kings and 6H as no king (which would be ironic, as I too prefer this) and concluded we were off the rails after looking at clubs King. Although both hypotheses contrast with the apparently normal explanation proferred for 5NT.

That is rather sad indeed
How many tricks does it need
It clearly is not simulating anything - and I agree with above sadly plausible hypothesis
EDIT I have put it through another bidding engine, tried coaxing various auctions but it could not get past 6 spades or hearts. Methinks there could be a market out there. Basic test. 15(?) top tricks DD -> 7NT. I sometimes miscount myself. Is it 15?
