Thanks for the tips. I am beginning to think that while bidding is a critical part of what makes Bridge interesting, it is also its Achilles heel. For my part, I never thought that glancing at the opponents' bidding card before a session was sufficient to capture what they are doing, especially if they have some unusual features in their bidding. Having a photographic memory would be helpful, but I don't have one. If you have to ask one apponent what his partner's bid means all the time the it damages the flow of the bidding, besides which it affords the opponents an unintended means of communication. The ACBL has outlawed some conventions (such as the strong pass/weak 1S system), presumably because they are too disruptive. BIL (and others) outlaws psychics. Having a system that is designed to disrupt the opponents' communication is allowed as long as it isn't TOO disruptive. Kind of like NASCAR allowing innovation but not TOO much innovation... Anyway, playing with the robots has rubbed my nose in this aspect of Bridge which I don't seem to like very much.
