I was a member of Ken Uston's team of Blackjack players and counters and I can tell you that although Ken was a programmer who ran his own computer analysis, the book we consulted was this book, "Playing Blackjack as a Business" by Lawrence Revere. This is still the book that I recommend anybody who wants to learn to play Blackjack well. As a member of Ken Uston's team, I can tell you that this Revere book is the book that Ken Uston studied. One of the reasons why the Revere 14-point System is effective is that almost nobody knows it. Anybody familiar with Thorp's Basic Strategy can immediately see whether a player is following that strategy. Also, the Thorp Plus-Minus System depicted in the movie 21 is fairly easy to detect.
