6NT
This is silly bidding but..

Robot leads a small ♦ from Jxxxx with ♠A86 ♥ AT9 ♣ T9
i have 7 running ♣ partner has AKQTx of diamonds
lead brings us up to 11 tricks
now run all the ♣ and GIB is squeezed out of an ace or J♦
Unfortunaly my partner didnt find this play

GIB's algorithms don't really lend themselves to human-like rules like "if on lead vs. 6nt with 2 aces, cash 2 aces". It's dealing out sample hands that fit the auction, and then picking a lead that does best on average, and probably cashing out leads to fewer undertricks on average and thus doesn't do it.

Probably its sample here for opponent's hand is unrealistic, because it probably defines 6nt as some massive number of balanced HCP which is incompatible with holding 9 HCP. Perhaps there could be some logic added that "if cannot deal hands consistent with bidding based on HCP, make up for it with extra shape", somehow, thus assigning the opp some large number of clubs and thus get it to see greater upside in cashing out.

this seems to be a very common complaint for the bots
not taking their setting tricks against 6NT and 7NT at tricks one and two.

at least you werent on lead not that really helps

I love how it's intelligent enough to double, but not to actually take the aces!

if one spends alot of time looking at results.....namely what other people do on the same
boards you will see alot of instances where GIB sets up his own suit and doesnt take like
2-3 setting tricks against 3NT...so it happens quite alot.
