Some bridge players -- like me -- like to experiment with advandced bidding methods. Sometimes one may envision several possible solutions to a problem occuring in one's bidding system. The only way to find out which works best may be to test it out in practice. The "Partnership bidding" function on BBO is an exellent tool in this respect. The only problem being that if you want to test something out without your partner being online you're stuck, since "Partnership bidding" doesn't allow you to take both seats yourself. The obvious fix is to allow one player to take both seats at a partnership bidding table, just like one player can take all 4 seats at a teaching table. I can't imagine this fix will be much work for the software developers. Another way to go, though, would be to include the possibility of setting constraints in the form you do at partnership bidding, when creating a "Teaching" table in the main bridge club. This, I believe, could improve the usefulness of the "Teaching" function a lot. Then, if you want to give your students itensified training on some specific bidding sequences, all you have to do is to create the proper constraints and activate them on your teaching table. Since you already have the "contraints" feature at parnership bidding, I don't think activating that feature in connection to teaching tables would present a big problem for the developers either. Actually, while you're at it (? ;) ), why not implement both?: 1. Enable the same person to take both seats at partnership bidding tables. 2. Augment teaching tables with the constraints feature. I expect 2. to be a somewhat more demanding task than 1., but then it will also probably be a feature appreciated by a larger group of the BBO users. At the end I just want to say that I am very impressed by the BBO software already!
