I want to take BJJ, and at some point I will, but at this time I don't have the money or the means of transportation. Regardless, I'd like to read up on it, and possibly practice a little with some of the people I train in karate with. So, anyway, I found these books, Brazilian Jiu Jitsu Basics and No Rules Brazilian Jiu Jitsu by Gene Simco, and was wondering if anyone had any thoughts on them. We actually did some groundwork at the karate dojo that I train at. We just free-sparred for a while. I'm new to grappling. so I apologize if I sound naive, but I'm very interested in learning.
