basic TKD
Chon-Ji is the first form that many of us must master. Sometimes it is too much to take in and one wishes that they could see the whole thing particularly the places where they have trouble. Jhoon Rhee's book is a big help. It explains the moves and shows them from different angles but more importantly he explains the martial applications. Too many people do not understand this aspects of the hyungs. Remember that you should do each form several hundred times before testing. Jhoon Rhee's series should be in any good TKD library.

First and best ITF forms books
Jhoon Rhee's series of hyung books were the first in the U.S. documenting the ITF forms. Except for this first book, these books present two of the forms for each belt up to 1st degree Black Belt. This book uses the rest of the space to demonstrate the basic techniques.

Overall, excellent presentations of these forms, especially the photo sequences that show you the entire form on one page, which is very useful for quickly scanning the form. Also, the author indicates where the kiai should be, which other kata books I've seen neglect to show you.

A good reference and teaching aid
This entire series has become a staple in our class for the last 10 years. Easily understood, with pictures from every possible angle, and diagrams as to how you should look between moves allow even my begining students to use it. For those studying this series of forms, this book, and its series, are a must have.

very well thought out book with excellent illustrations
Very well illustrated book by the father of tae kwon do in the United States. Jhoon Rhee shows why he has been considered the master of this art and a teacher who has been emulated by many from coast to coast and throughout the world. I never thought you could really learn a martial arts form or anything useful about martial arts from a book until this one came along. Wow! Even accomplished students of the martial arts would gain excellent insight into their art by having this book. Newer students will improve their learning and understanding of what they are doing by being able to review this book while they are learning. The only way I can think of improving this book is by getting it autographed by the author.

Well illustrated
My first impression was one of disappointment. I had anticipated a book demonstrating the hyung patterns, rather than a book demonstrating the various techniques applied in them.

Once I was over that first batch of disappointment, however, I came to appreciate the book for what it is worth -- a good book on illustrating ITK moves. I liked the way the photographies are handled, with overhead views as well as side-views.

It was not what I was looking for, but a good book never the less. I recommend it.
