"The material is what makes this book very good. Emms annotates 46 games to present the material. What set this apart for me is that as I read the material I felt as if the author was actually talking to me, trying to explain what bits and pieces are going into the choice of moves. There are notes that involve some calculation, a few are even somewhat involved. Yet it works well to make the system seem easy to use, if only the reader invests the time to go through it."
