There are better books than this.  The book is way over priced for the amount of information in it.  The seven circles is only for someone who can devote many hours a day, and eventually several complete days to doing tactical problems.  If you are expected to work and maintain relationships perhaps you may find the seven cirlcles to be a bit much, I did.  But my problem is not with the material in the book, just the fact that theres not much there and you could probably do just as well searching the internet. 

While I would agree with my fellow critics that this book is about tactics and vision. I would also emphasis that this is not a book for all level of players. This book is definite meant for strong immediate and higher players. Not anyone above a rating of 1975 or below 1600. Its meant for players who have opening knowledge and may be weak in middle game play. The author said that if you follow his exercises, you can increase the strength by 200 points. I download an example of the software he recommend and I have to admit if I could just incorporate it into my game. I believe I could improve my game a lot. So I recommend it but it's not for every one!

I have been told that just about everyting in this book can be found in the columns at www.chesscafe.com

I was really excited about this book when I started reading it: "Finally, a book that will give me the answers I have been looking for!" How disappointed I was a couple days later. The entire book is based on the premis that board vision and tactics will make you the best you can be. There is no discussion of opening theory or endgames or even middlegames. It is all tactics and board vision.

 Have we heard anything else from this author since?

I bought this book because it is strongly recommended in the media, but I didn't like it. It only say, basically, that you must master tactics in order to be a better player. It then give you a basic plan to get it, based mainly in the repetition of a collection of exercises. Nothing new, isn't it?
