Betting patterns aside, the only real "tell" (used loosely) you can get online is the time it takes a person to act.
This will only likely tell you how many tables they are playing.
Or if the phones ringing or his computer froze.This will only likely tell you how many tables they are playing.
Very fast or very slow typically means very strong or very weak. I will (on purpose) sometimes let the time run down when I have a very strong hand. This is a great act. I will also bet quickly when bluffing. I have found some quick betters to be bluffers too. But it has to be taken into context.. if there is a straight on the board or flush possibility then I'm probably spending the time for real to consider what I want to do.
For many players at microstakes weak bets are strong and strong bets are weak BUT not all. I will often bet big when I have an unbeatable hand because I want to look like I'm drawing or trying to stop one from betting.
If a player is giving themselves free cards on a board then often they are searching for trips or they don't have anything and are not interested at all in the hand.
Also multi-tabling doesn't automatically mean the person's a shark. All it really proves is that they think they're good enough to play multiple tables at once. They aren't all that good, not at the lowest stakes. Maybe higher up they are, but not down low.
