An older but useful book on BJJ, some sneaky techniques by Bravo
Despite Rogan's and Bravo's ignorant comments on TMA (Karate in general) in the book, as well as presenting BJJ as a complete martial art (without striking you will probably not do well in the cage or the street). the rest of it is useful for a BJJ fighter. There are many sneaky techniques from half guard and rubber, great for a shorter person to pull off. The pictures are not always taken from the optimal angle so you may need to use your brain to figure it out, not hard though.
