Query: Blackjack For The First Century

One usually assumes that if a person has written a book, he or she must have a modicum of knowledge about the subject being written about; but this book proves the fallacy of such an assumption. John Patrick is totally clueless concerning the mathematical probabilities which govern this game.All games that are offered by a Casino have a built-in advantage, but seldom will you find an author suggesting that you play in a way that will increase the Casino's advantage over you. This is the only thing that John Patrick does correctly. Every one of his "special" ideas about how to play this game are WRONG.If you play Blackjack the way he tells you to, you will not only throw away the money you spent to buy this book, you will also throw away the money you wager in a Casino using his "special" strategy. My only regret is that I had to choose a rating system from 1 to 5. If I could, I would have chosen -50.
