But are you saying that Gib will sometimes randomize between which option to choose?

The hand where Lycier's West bid differently than all the others was not in a tournament; it was in the Main Bridge Club, or another club. GIBs will always behave the same under identical circumstances within a tournament, but there are variables in a non-tournament environment or across different tournaments.

However, I have mostly looked at pure robot-tournaments (always 1 human + 3 robots at every table),
so it might be that BBO for some reason
is not using the same approach when a robot is playing in a competition
with a mix of human-human and human-robot pairs, like your example shows.

In the main bridge room where people rent robots, some rent basic GIBs and some rent advanced GIBs. Basic and Advanced GIBs can bid and play differently.

OK, thanks Bradley. That's about what I figured then
