Author propounds and briefly illustrates the basic principles which we think we know but often overlook in the heat of tournament combat--- simple things like development, control of the center, not wasting time with unnecessary pawn moves. He talks about how to exploit White's initiative, and how Black can take control if White plays incorrectly. Now, translating his few examples into actual practice in your own games will take a lot of over-the-board practice.
