another essential for your combat sports library. bj breaks it down, including mma techniques not currently allowed in the unified rules (he teaches knees to the dome on downed opponents, soccer kicks, etc). but lots of great mma jiu jitsu including his 'damned good guard'. also, great intro where he tells the inside scoop about his background, training, and a lof of his fights. the pics and overall organization of the book are great.
