Poker Legend's E-Book Is A Must Read - If they give an award for the best poker book of the year All In: An E-guide To No Limit Texas Hold'em, by Amarillo Slim Preston with Brent Riley is it. This is absolutely the best poker book I have ever read. And I have read a lot of them. I expected a lot from a man who won the main event in 1972 and was Doyle Brunson's partner for over 20 years and I wasn't disappointed. This book is not only informative but very entertaining it has a flavor that only a great story teller like Amarillo Slim Preston can give it, and it is full of tips that only someone of his experience and knowledge of the game can give.
