Book excerpt: Is there really such a thing as a professional gambler? The answer is an unequivocal, "Yes!" This book's authors are but two examples. Many thousands of people around the country make a good living exclusively from gambling. It is not easy, but it can be done. The key is to understand which games are beatable and know how to beat them. David Sklansky and Mason Malmuth have spent many years writing about the finer points of poker, blackjack, and other beatable games. As you will see in the book, those other "games" are horses, sports, progressive slots and video poker, casino tournaments, and special promotions. They don't include craps, roulette, keno, or baccarat for reasons they'll explain. This book, was written for the not quite as experienced aspiring gambler. It shows you everything you need to learn and do if you want to gamble for a living from both the practical and the technical standpoints. The rest is up to you.
