This book is in the category of "win without card counting" blackjack books. Like other books in the category, this book contradicts conventional wisdom that the only winning blackjack system involves "card counting". Different from other books in the category, this book offers "proof" of winning in the long run. With apologies to Kenny Roger's "the gambler", a parody in the book describes what a blackjack player needs to know and do to be a winner, on average, in the long run.
Don't want to count cards to win at blackjack?
Replace card counting with a "bailout" strategy.
You can either use flat betting, up the bet after a winning hand (positive progression) or up the bet after a losing hand (negative progression) to win, long run, provided your choice is combined with a tailored bailout strategy.
Contrary to other books on the market, this book offers "proof" of its winning claims.
