In short, this book contains absolutely no useful information. John Vorhaus complains that there are a pile of online poker sites out there with a pile of players all eager to take your money. Well, it looks like John Vorhaus is eager for some of it too. All he's done is jump on the poker train and he's laughing all the way to the bank. Kudos to you John for bluffing me with your book title. You had me at Crushing . This book will not help you win or provide you with any information to better your playing style. My advice? Use your $20 to buy any other poker book on the market, or deposit it onto a real online poker site to get some real online experience.I have not read John's other Killer Poker books so I cannot comment on them. However, I did read this one and it sucked big time.
