Just checking - when playing live tournaments it's okay to discuss in between hands specific hands/players with your friends who are watching on the rails right?
But them signaling you in any way during a hand would be frowned on correct?
ok, I don't really have loud discussions about the play at the table - just might walk over to the rail after i fold a hand and chat a little about the previous hand - can't see anyone getting annoyed at that.
It's often the case that people not involved in a hand can pick up tells better than someone involved. For that matter, people on the rails can often see the cards of the players at a table (someday that's going to become an issue at the WSOP when someone is caught signaling to a friend from the rail). So yes, signals from the audience would be "frowned on".
Whenever anyone I don't know asks what I had, I tell them they'll get to see it on TV. It's good for the game.
