The first book in Zachary Elwood's acclaimed poker tells trilogy, Reading Poker Tells will teach you how a professional poker player analyzes the facial expressions, body posture, physical gestures, and verbal statements of their opponents. Besides cataloging the meaning of the most common poker tells, this book gives a mental framework for thinking about and remembering tells. It also contains information on general poker psychology, methods of manipulating opponents, and methods for becoming unreadable.

Ask the great poker players how they'd play a hand and the answer is always "it depends." That answer can be infuriating. But guess what? It really does depend. The key to becoming a great poker player is in knowing what it depends on. At last there's a book that gives you that answer. Poker is a game of so many variables; table position, flop texture, the number of players in a hand, the personalities of your opponents, and so much more.
