And I certainly do not agree that the best solution in such cases is to always pass. It is also worth noting that the game forces both partnerships to play using the same bidding system. As I already mentioned, you can go back through bidding sequences, or check their meaning via a menu option. Declarer play can be classified the same way. The computer plays pretty well in ordinary situations - which is again not a surprise.
Deceptive plays are of course out of the question.
Comparing it to my real-life knowledge, I believe that Bridge Deluxe 2 plays at about novice club level, but without the really stupid lapses. Inconsistently, yes, but it happens. Of course, since the game does not even mention defence anywhere, I had no idea when to expect them. This attitude fits well with the general, novice, level of the game, and is a very common attitude to be found amongst beginning players. I do find it distasteful in a program that is supposed to teach one Bridge, though.
