I heard about a book on tells but can't remember the author. Tells are only good on live playing. I defy anyone to have a definitive read for line tells. Google around and I am sure you can find the book you are looking for to buy on line. If you want to learn the game and win invest some money in some books and commence to read. Brunson's is the best. Any poker book will get you started. There is no teacher like experience and this experience has to be for real money. Play chip is only good to see the limitless hand possibilities. It will also show you a lot of showdown luck.
