Rules & Etiquette
Keep the noise to a minimum!
If you talk about something not related to the hand in question during play, you will distract your opponents, your partner and yourself.
If you have finished, remember that other people may still be playing, and lots of background chatter is very off-putting.
If you are discussing a hand that you have just played, remember that other people in the room have still to play it, so don't let them hear what you are saying!
