A treasure trove of behavioral information to give a huge edge over the competition, this guide teaches how to read tells—the subtle ways in which opponents betray themselves through body language, table talk, chip moves, eye contact, and more—in order to increase chances of winning in poker. Tells are rarely obvious and it takes concentration to find them, but this book shows how to identify them and use them to an advantage to exploit others' weaknesses and win pots by betting or raising at just the right time.
