1. Old BBO version. If you use the old, downloaded BBO, it runs the GIB program locally on your PC. The speed of your CPU is a factor, because GIB limits the amount of time it thinks on a hand, so slower computers will do less thinking. You can also configure the thinking settings.
2. New BBO, basic robots. These are the robots you get when rent for $1/week. They don't do any simulations during the auction, and use a less sophisticated play algorithm.
3. New BBO, advanced robots. These are the robots you get when you rent for $1/day. They simulate during the auction (when the bidding rules allow) and use a more advanced play algorithm after the first few tricks.
Also, the simulations used during bidding and play make use of randomly dealt hands, and the random numbers will be different at each table.
Things are less variable in robot tournaments. These all use advanced robots running on the BBO servers, and the same random hands in simulations (as long as the human bidding and play are identical).
maybe there could be a way when looking at results to see what kind of GIB
is playing.....
say
RED-old
GREEN-new
BLUE-advanced
I tend to rent GIB by the month and just look at results like playing in a club or open game where there is always an odd result or two.
When playing in ACBL bot games the play is more reliable, but the bots are more advanced.....but some times when I go over results I wonder
why GIB does the things he does at other tables.
