The basic information which he outlines is good,but somewhat outdated.His "system" for winning flat out doesn't work. I tried it for two weeks. I tried it on different games, different casinos,no,the losses out numbered the wins.It isn't that difficult to learn so its not like I wasn't doing it right.This book is a little dated so maybe the casinos changed their programs since he published. I don't know,but bottom line you can not come out ahead using his system,believe I wish you could.
