Video Poker: Optimum Play

I purchased this book because I saw a TV show that said "Video poker can be beat". I found this hard to believe but it is apparently true on some machines with perfect play. Ah, there is the rub. Along with the book I bought a computer program that teaches you how to play and shows you each error you make. It isn't real hard to learn how to play perfectly but requires a person that can really keep focused for hours on end. Most folks with the intellect to learn this could make much more money doing something (anything ?) else but if you have to gamble this is your best shot. This book with Frugal Gambler and some real effort will make your Vegas trips more fun. I don't think Vegas casinos enjoy losing so I wonder how long this will last ?
