This is not a book in the traditional sense; it's really largely an anthology of Schlesinger's "Gospel" articles from Blackjack Forum magazine, dating back to the 1980s. Because of this, it's somewhat lacking in integrated cohesiveness, but it's a very valuable resource, nonetheless. Schlesinger covers most of the statistical aspects of Blackjack in a clear, concise and accurate fashion. In addition, Chapter 10, which is primarily the work of Schlesinger's collaborator, John Auston, is all-new and presents some very comprehensive game-selection and risk-of-ruin charts. All in all, an excellent and very useful resource for serious players.
