Yeah that's a cool site.
A friend of mine recently got into the game and was almost more interested in learning the 'cool' tricks the pros do on TV, than becoming a winning player! lol. he went to the casino and bought 15 1 buck chips to practice while playing on the net... I thought it was funny

.
He has since learned how to do most of the tricks well, with at least 70 percent success rate, but he hasn't become a winning player yet (and I am starting to wonder if he ever will...)
Cheers,
