Let's admit it, this is an annoying one, especially when you're rolling against a very long-legged opponent and, unfortunately, they took your back. But, thankfully, part of jiu-jitsu is about the ability to escape the most uncomfortable of positions, so there is always a way out.
Richard 'Monkey' Nancoo is one of the 'old school' black belts in Canada. He's been through a lot and has some awesome stories to share. But below he is going to share this nifty trick he likes to use when escaping the body triangle. Of course, there are always various other options you can use, but give this one a try and see if it suits you.
