This book might be encouraging for someone who has never won at all and needs a push to do so, but it contains very little real information other than to be aggressive. I read this book with a highlighter pen in hand and only used it a half a dozen times or so and I was being generous. It reads much more like he sat around and talked about how he likes to play and then had somebody type it up than any sort of useable strategy advice.
A little information is a dangerous thing...and this book reads like he wants you to have just enough of his attitude to think you can play him, but he doesn't want to give you enough insight to actually win. You are left with the feeling that he has withheld much more than he has shared. I for one would be happy to think that my opponents were basing their strategy on this book.
Be aware also that this book is shockingly padded. Listed as 191 pages, Erick Lindgren wraps up his portion on page 129, followed by 30 pages of completely irrelevant and instantly outdated useless lists of WPT money leaders which even if they were helpful could easily have been condensed into 2 pages tops. Next comes 20 pages by his co-author which delve into all sorts of math that can be replaced with 2 simple charts that are included.
Very light on content, I would rate this a definite pass. It mostly is beneficial to show that if you DO win on the WPT, you will get all sorts of cushy, fluffy, lucrative offers to cash in away from the poker table!
