Eddie Bravo's approach to jiu-jitsu is novel, and something that anyone could beneficially incorporate into his or her own jiu-jitsu game. That being said, I would say that this book isn't really geared toward the beginner. Eddie doesn't go over the basics of jiu-jitsu. Rather, he assumes you know the basics and are looking to add something new to your game. Furthermore, being in the 150 pound weightclass himself, Eddie has a lot of good advice for those practitioners that are in the lightweight category. The book is filled with large, black and white pictures. Too often jiu-jitsu books are filled with small pictures in which you cannot see the details of the moves. In "Jiu-jitsu Unleashed", although black and white, nearly every picture is at least a half-page in size, and many are a full page.
In the introduction, Eddie tells his personal jiu-jitsu story, from high school wrestling up to his defeat of Royler Gracie in ADCC and on to his creation of the 10th Planet Jiu-jitsu school. As a self-described "150 pound weakling", his story is inspiring. And he makes a very, very strong case for training without the gi, his argument being that avoidance of gi training is responsible for his meteoric rise in the ranks of the submission grappling world. I don't think this is the whole story, however, as Joe Rogan points out (correctly in my opinion) in his introduction that what makes Eddie Bravo great is that he is naturally creative and not afraid to experiment and invent new techniques. In my opinion, Eddie's personal story alone makes this book worth the price of admission.
Next comes the instructional segment of the book, which is the majority of the book. Eddie begins with the half-guard, and here he asks: since so often players spend so much time and energy attempting to reposition from the half-guard to the full-guard, why not just learn to fight from the half-guard? I think this is a great approach.
From the beginning, Eddie sets a precedent for the rest of the book. He first explains why he is about to teach you what he's going to teach you, and when it is to be used. Then he explains how to do it. And finally, if it doesn't work, he goes on to the next move, which is "plan B", then to "plan C", and so on. In this way, I feel he has done an excellent job in building up the jiu-jitsu game like it really is: a sequence of moves that act like a flowchart, giving you options for the various possibilities that arise in a real grappling situation.
Next, Eddie discusses his variant of the full guard, called the rubber guard. This is essentially a clever version of the guard that allows you to trap your opponent in your guard without relying on grabbing ahold of the gi to do so. Rubber guard has become quite common and can be seen often in mixed martial arts matches like UFC. This move, like many in the book, is victim to a cheesy name. Even if all of these moves do become popular and ubiquitous, I hope the names don't stick.
In the third chapter, Eddie introduces his trademark move, The Twister. I appreciate the fact that Eddie is not selfish with his winning moves. Throughout this book he takes on a very selfless attitude in which he bares all in the hopes that everyone will learn jiu-jitsu as well as he has.
In the fourth and fifth chapters, Eddie goes over some submissions from the mount and from back mount, respectively. Chapter six deals with guard passing. Compared to the first three chapters, these are pretty much standard jiu-jitsu fare, though I like his over-under approach to back mount.
In chapter seven, Eddie brings the entire book together. As anyone that's done jiu-jitsu knows, things never work out in reality like they do "in the playbooks". Therefore, you must be prepared to move from one strategy to the next. In the last chapter, Eddie does just that, by showing you how to transition between each of the positions he's described in the book and back again. This chapter really ties the book together, and gives a reason for the inclusion of chapters four through six.
The only reason I'm not giving this book 5 stars is that I felt it lacks as an "all-around" guide to jiu-jitsu as advertised in the subtitle. Really, the primary focus of the book is half-guard, rubber-guard, and the Twister. Don't buy this book if you want to learn jiu-jitsu basics and the entire jiu-jitsu game (for that I might recommend Royce Gracie's new 2-volume book series, or something by Royler and/or Renzo Gracie).
I highly recommend this book to anyone that is looking to add something new and interesting to their offensive jiu-jitsu game.
