This book features many, many techniques, but it is not intended for the beginner. You won't find much instruction, mostly composed of one series of photo's depicting one technique after another. For the experienced Judoka/Ju-Jitsuka, this book deserves a 4-star rating; for beginners, or those interested in learning more about the art of Ju-Jitsu, this book ranks a 1-star rating. This is NOT a how-to book, nor does it contain discussions of ethics, legal consequences of your actions, nor does it discuss the history of the art much. If you have a few years of Judo/Ju-Jitsu training behind you, this book will be VERY useful in expanding your repertoire. With 10 years experience in Judo and Ju-Jitsu, I find Tegner's books helpful, but sometimes difficult because of his editorial comments. Most of his books are better suited to experienced martial artists, so choose carefully.
