Why play a free online poker card game? If you've got experience in casino poker, you'll probably think a free poker card game is a waste of time. But think about it: the pace of online play is different than casino play, you're not worried about "tells" that happen in face to face games and any mistakes you make are free!
The real secret to online poker is learning the tells that only happen in online card games. Keep in mind, there are automated features in poker rooms that can give you an edge, not by using them, but by learning how others use them. A disciplined, smart player will quickly pick up the habits and mistakes of less disciplined players. This won't happen overnight, which is why taking the time to play free online games can help sharpen your eye for those tells.
Once you get a real feel for how others use automated play, you can begin to craft a strategy for using them effectively yourself. Just by thinking in terms of bluffing and misdirection, you can develop ways to send deceptive messages by your automated play. Whenever a player seems to switch from automated to manual play (or vice versa), that's a tell. The question is: what does it really mean? A clever, sneaky, underhanded and treacherous player will use that "tell" in the opposite way it might be interpreted.
Taking the time to rehearse your bluffing strategies and tactics is never wasted time. A free online poker card game will give you some practice, along with small pot games. Then, you can up the ante and take the winnings to the bank!
