I apologize if this has been addressed, but I have been on the site for years, and know that I have seen many more players, in total, who use SAYC as a bidding reference, whether or not it is their preferred system, than I have seen players who use 2/1. This said, why then is 2/1 the system that was chosen for the GIB robots to use? I feel that there should at least be a choice between 2/1 and SAYC, since, as above, many more players the world over know it. I understand there are other systems, and am not trying to begin a gripe session where everyone wants their own system as an option. However, it seems like an arbitrary choice made with little forethought and certainly little member input.
