Firstly I bought this book based on the rave reviews here, my expectations were high. I have now read through the entire book and I have a real mixed feeling about this book. If you are expecting pictorial examples with step-by-step guide, then you will be wrong. The images or line drawing diagrams are crude and too basic and perhaps not very clear.
The author is very critical of martial arts and artists which he sees as not effective or martial arts serves little in 'real' situations. The techniques the author explains has all the hall marks of martial arts. Parrying, side steps, back fists, knee strikes, trips, it what I have been taught by my instructors. There is a lot of text and blurb in this book. Sometimes a little too much, especially as lot of his descriptions or examples are in narrative jokey jokey style. Due to this, the book is more like a novel.
Where this book is good and worth reading is the invaluable experience the author has. He makes lots of valid points and his vast multiple experiences shines light on these situations and how to deal with it. I would have preferred if he was just more to the point and used less words.
Buy this as an additional read to broaden your knowledge, but if you are looking for self defence techniques or you are a martial artist who is looking for techniques, perhaps you may not find the answer here. I would suggest to look at Hapkido and small circle Ju Juitsu techniques.
