"Chair" was a reference to the OP (Answer: Pull up a chair beside your roommate, sit at a 25/50 ...).

And I am not so sure that you neccessarily have a stronger urge to collude if you sit in the same room. i often played at my friends place while he was playing, too, and it never occured to us to sit at the same table and help with information.

I rather think it's a matter of attitude: Colluders will always try to collude, whether being in the same room or communicating by other means. Honest Poker players won't (in fact, those won't even touch another account even if someone left it logged in accidentally)
