Tells in online poker
Obviously there are not as many tells when playing on the internet as there are when playing in person. You cannot see the other player in order to read his/her expressions and emotions. But believe it or not, there are times when you can pick up on the playing habits of another player online. For instance: Players that frequently push the check/fold button before their turn. This is very common among novice or uneducated players. This is an easy tell, they have no hand worth playing and only hope to see free cards - or fold if a raise is made.
A good player will take some time off of the clock even when they have nothing. This keeps the other players guessing at all times. Sometimes it will even frustrate an experienced or frequent player causing them to make a hasty decision. If you see someone checking quickly hand after hand, play them aggressively, unless of course you know the player and they are using this as a method to fool their opponents.
Some veteran players will try to use the clock as a "timing" tool to their advantage. For example, a player may take the full "time out" before they make their decision to check/fold/raise. If they use a large amount of time to simply check, odds are they have nothing. Slightly raise the stakes to keep them in check. If they come back with a large raise or an all-in raise
