In this book, Bas Rutten focuses on the groundfighting and submission game of NHB. His chapters are extensive, using decent black-and-white photos to demonstrate his holds. The chapters focus on one body part or subject at a time (for example, "Escapes" or "Arm and Wrist Locks"), and most run about 100 pages long. The sense I get is that Bas really cares about making sure the reader understands how to perform the moves correctly. On the plus side, he shows quite a variety of different ways to enter in to these subs, and also shows how strikes could compliment the subs. On the down side, there is little in the way of new or different holds being shown, and the quality of the photos and print are below what I'm used to. Of course, that doesn't really take away from what's a very good book overall.
The chapter on escapes was especially good, since every escape led to a better possition and sometimes a hold. There was a nice chapter on stand-up to ground combos that I think is worth looking through. I thought the chapter on banana bag combos should have been in the first book, though. Also included inside the chapters were blank lines that could be filled with training notes.
Overall, a very good book, and a good compliment to Bas's first BBOC. The fact that the holds were given generic names could prove confusing for training purposes, but if done propperly, they are very good holds indeed, and the book provides more than enough for either beginners or advanced.
