The author recently published a videotape (sold at $200) with cheating techniques, most (if not all) described in the book. The book has been praised favorably, and the techniques it explains are very good (altough not all easy). I think it will become a classic on cheating, like the Erdnase was (is). The techniques are explained a little "tersely" and more (and better!) illustrations would have been better. It describes however a great blackjack stack from a new deck, and a good blind shuffle. Requires quite good knowledge of Blackjack, though.
