I've seen quads twice in a live tourney with only about 30 or 40 players. What are the odds of that? I've had and seen someone else have had AA in the hole back to back live. What are the odds of that? I'm not saying it is or isn't "rigged" online at some sites. But, they are going to earn revenue without cheating, so the risk of getting caught and losing your business seems unworthy the acceleration of profit. If you keep a catalog of hands and show that mathematically the percentage of outcomes is very askew or by some means show some sort of compelling evidence that the game is "rigged" I'd love to see it and it should be shared. But, if your really worried and can't prove anything, stick to the low limits and just try to enjoy the game or go play live.
