Geoff, very bad form to give your own book a good rating. Worse still to attack someone who spent money on it.
The book is supposed to be about Internet gambling, yet you only mention seven casino sites and even then only in passing. (pgs 72, 73) You also say that they "pass muster with the watchdogs" but one of those seven is Golden Palace - very well know by the 'watchdogs' as having seized thousands of dollars of players monies with no recourse.
About a third of the book is devoted to British horse and dog racing sites. Not very useful to the majority of gamblers on the Internet who are looking for casinos.
There is nothing - nothing - in the book that cannot be had for free on the Internet at any number of sites. Just because I wasted my money on it doesn't mean that others have to suffer the same fate.
And, if the book has been so well received in the gambling community, then why aren't there any positive reviews? (other than your own, of course). I could have written the book in a weekend, as I'm sure you did also. It is not completely without merit, but for anyone who is serious about learning Internet gambling, they would do better elsewhere. You should try again and put more thought/effort into it. There is a need for one other decent book besides Bill Haywood's offering.
