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.
