With Chapter 4, we get into the heart of the book. Andersen has studied the betting and playing habits of big bet blackjack players for many years. Based upon these observations and some computer simulations, he has devised a playing pattern that provides excellent camouflage while maintaining a healthy edge. In addition to the explanation and defense of this strategy, several chapters also cover changes Andersen has noted in the way casinos respond to the threat of counting, and how he has evolved his techniques to compensate. Even when the material had previously been covered, usually Andersen's observations are fresh enough to be worth reading.
Some chapters are less substantive, but no less fun to read.
For example, one chapter covers unusual things Andersen has seen at the tables. Most of these are quite amusing, although few will help one play better blackjack. The author has probably seen a great deal more of these situations, and if he wrote a book just about them, I'd buy it. He also talks about sports betting, although, this is more entertaining than useful, but entertaining it is. The final chapter deserves some mention.
