If you are going to play low limit hold em forget the books on tells and try Lee Jones book.
Winning Low Limit Hold em 2nd edition
I read this book before going to BELLAGIOS . I bought into a 2/4 limit with $100 and in 2 hours I doubled my money while the other players kept pulling out their wallets. Maybe beginners luck. But I really had no experience before this and I played by the book and I'll give it credit.
