Books on Poker Tells and/or Related Subjects
Former FBI agent Joe Navarro wrote an excellent book on poker tells called Read Em and Reap. It’s short, easy to read, and a must-have for any aspiring poker player. His book What Every BODY is Saying is also an excellent guide to body language.
You can find Zachary Elwood’s books Verbal Tells and Reading Poker Tells at his website Reading Poker Tells. There are also courses you can subscribe to through the site.
Mike Caro’s website at Poker1.com has lots of information on poker tells from the original mad scientist himself. Definitely worth a look.
I will add more to this page as the site progresses.
