In hand one of the Weekly Free Solitaire after 1d-1h-1nt the robot has shown 12-14. Now 4nt by me asks Gib to bid slam with a maximum but if fact with only 12 points and a 2-3-4-4 hand it bids 6nt. Hardly a maximum! That it does make doesn't mean that it's correct.

That's not how GIB works. It doesn't understand ranges. It just thinks 4NT shows 19 pts or whatever, and simulates from there.

A basic robot would pass, since it does simply accept based on point ranges - they're told to accept with 13-14, and pass with 12. But the weekly free is the only free tournament that uses advanced robots, and they simulate hands that you could hold to see whether it would work better to stray from the normal acceptance logic.

Opposite hands which have 19-20 points as the description of 4NT shows, the specific 12 count that it held - prime values with Qxx in your suit and and AKK outside - has 6N makeable more often than not. Most other 12 counts it would find to be an easy pass.

While this is double dummy based which will affect the odds, theoretically, this sort of situation is where robots should do better than humans who just count the points.
