The book explains how the author went from Class E to Expert in two years in a three-phase program. The first phase is a series of drills, such as putting the knight in the center of the board and finding the least number of moves to get to each square of the board, to be repeated over and over. Many people might feel a little dopey, not to mention bored, following through on this. And the drills are not really explained in detail, nor are any answers given. The second phase is to buy the software CT-ART (purchased separately) and go through its 1000 problems 7 times. The book suggests a particular schedule for doing this, with each pass twice as fast as the preceding. The third phase is some simplistic strategic guidelines (since the author's own experience was that he actually couldn't quite make it all the way to Expert just with tactical training). The book strikes me as more on the lines of a motivational, self-help kind of work; there's not much chess in it.
