Xande Ribeiro is one of the best grapplers in the world. Having won the World Jiu Jitsu championship open weight division twice and the heavyweight division five times, he has rolled with the best grapplers in the world and come out on top. So when he says his diamond guard side control escape will show you how to pass any side control, you should listen to what he has to say.
This diamond guard takes a lot of abdominal strength, and Xande talks for a while in the video about his workouts and how he keeps his abs in shape. He also mentions that his guard has not been passed in competition since 2005, so while this side control escape might be tough at first, it is proven.
Start: Side control bottom
Step 1: Wrap outside arm around opponent’s back, holding tight and maintaining a constant pressure so that you move with any pressure and when opponent pushes into you, it creates space between opponent’s hips and you
Step 2: Bring inside knee and elbow together across opponent’s waist
Step 3: Push off opponent’s hip with inside arm to create enough space to move inside leg into half guard or full guard
