ngsinan: Well, I like to play bridge, but I don't think I like to play bridge on a turn based site. Games on a turn based site should be those games where the current state gives you all the information necessary to play well. For chess for instance, only the current position matters, not how the position was reached (ok, except for the fact whether you are still allowed to castle, and for the 50 moves rule - but the latter hasn't been implemented). For bridge, it's different. By the time you get to play your 10th card, you might be six weeks away from playing the first card - well, then I won't remember whether you played the Jack or not. Besides, it would suck to be the dummy.
Furthermore, there are no 4 player games implemented here anyway.
