re: Poker & I ain't your friend.
I like Oz's answer.
If you aint in it to win it, fine. But most ppl are. Still, if it is a live game, you can be there to crush w/o having to be rude or unfriendly.
Tommy Angelo has spoken about his, and he seems to have 2 modes in a game. Mode 1 "I am in a hand" Mode 2 "I am not in a hand". And when he is in mode 2, he still respects the mode 1 of the table. But he will chat about music, w/e, with other players while not involved in a hand.
Put a different way, when you are in a hand, play your best, dont give any info while trying to get as much info as you can. When you are not in a hand, respect the other players who are, other than that, make your presence at the table pleasant and friendly.
IMO, trying to "out-psyche" the other players (by trying to tilt them with trash agro talk. or being a dick or w/e) is just live FPS in most cases, and most players who do this give away as much or more than they gain.
