I was looking for a book about Daniel Negreano's 'Small Ball' game, but I didn't find one. Instead I found this book of tips. After reading the book, I realize it's a lot more than '50 powerful tips;' it is a very good book on how to play Texas Hold 'Em poker. It was a good book that was very easy to read and understand. I highly recommend it for any beginning poker player who already knows the basics of how to play and just wants to learn strategy. Negreano doesn't touch on the rules of the game how to play at all, but he gives a lot of great advice on how to win.
As a player for many years, I am still always looking for ways to improve my game and I did find quite a few ideas in this book that will help me. I recommend it to any poker player at any level.
