Triangle Chokes

I was talking to a friend this weekend who was interested in my Brazilian Jiu Jitsu (BJJ) training but had no idea what it was. I posted a picture of an arm bar submission yesterday and while reading through my blog list today I found this picture. The guy on the bottom is attempting a submission via triangle choke. Basically you use your legs and their arm to cut off air and blood flow. Awesome, I know. I just learned this submission about a week ago and have already used it a few times. It could become my favorite move.
