There is a lifetime supply of information on tells, when playing in a live game. So far, I've only picked up a few on line tells. The Shover- he shoves when the board looks dangerous and he perceives the other players in the hand to be chickens. The Garbage Big Raiser- he is usually in 2nd or 3rd place after the big blind, and all have folded before him. Particularly likes to do it in the first few hands, before anyone picks up on him. The Instant Caller/Raiser - They are so excited by their cards they know what they'll do, regardless of players before them.
There's lots more, so add to this. By the way, I used he for convenience, it could equally be a she.
