The reason I like this video so much is that there’s nothing complex here, just good solid technique. Closed guard is an iconic position of BJJ. The back take and the mount are arguably the two most dominant positions. In this video, you learn how to go from one to the other to the other in a simple and almost unstoppable sequence. The best part is that you can rely on the fact that it’s rock solid technique, because the instructor is Buchecha himself. It doesn’t come much better than this, so go drill it.
