Poker Books and Movies
The only qualification needed to write a poker book is the ability to get someone to publish it.
There is a lot of junk available written by people without a clue about how to play winning poker. Some authors don't even play the game!
I don't "recommend" any book as gospel, but many present useful information that should get a reader thinking. That again is
a key to winning: think for yourself. Do not passively accept what any writer presents. Parrots are no threat at a poker table.
Besides Amazon.com, poker book sellers include:
Gambler's Book Store and
Conjelco. Check out
