I really like the Ezekiel choke. It was one of the very first submissions I learned and I’ve written about it before. It’s a marvelous way to get your opponent to take a quick nap.
It’s such a simple choke but it works for me again and again and everyone should know how to do it.
I was surfing around on BJJ Heroes and found a cool page about it which had this awesome BJJ video vault video by Rafael Lovato Jr. The instruction is clear and concise and the instructor is a legend. What more could you ask for in a BJJ video.
