Online collusion is definately there but you don't see it in your normal games. Its a lot more prevailant in the $100-$200 tourny's. I left a few of those games because you can see sometimes that 2 people are from the same town. All you gotta do is fold when your heads up with your amigo. or you can just throw your friend all your chips and noone would say anthing except, "what a newbie, what were you betting on?" and you instantly have a nice big chip lead. Its there but it plays in the shadows.
