Assumptions

Nobody who logs onto an online poker room is the smartest man alive, or the best poker player on the planet. This is not a slight against people who play online poker, but unless someone is the reincarnation of Johnny Moss, chances are somebody at the table with them is just as smart, just as savvy, and has just as much experience playing the game. A big mistake that many, many players make is to assume that the other people seated around the table are either not as good as they are, or are outright fish.
