This book is one of the most interesting I have read. It has many interesting points such as a revised points score scale for the pieces. Berliner clearly believes in this as he has used it for the evaluation function in his computer program HITECH.
Also some of the opening analysis is very interesting, such as some very convincing ideas on Benko gambit and Grunfeld.
The book is has been slated by some ignorant reviewers who do not fully understand what Berliner is trying to say in this book.
The idea in the book to me is that evaluation is the key to the middlegame and that you have to have an openings philosophy.
The anecdote about his conversation with Bobby Fischer is also an eye opener.
All in all very entertaining, more please Dr Berliner!
