De La Riva - it's a pretty sophisticated guard, okay? A version of open guard. Start off - I have my hand strong against the De La Riva. This is the De La Riva hook. It's important that you engage him immediately by pushing his knee like so. And now on this side I'm gonna turn my hand inside. Inside. And I kill that grip. Now I have both his legs, okay? And now I'm gonna drive my knee across. Notice that I'm keeping his leg trapped between my knee and my shin. I make sure as I cross I don't take this out. If I take my foot out, now he can just lock me in half-guard. You don't want to do that, okay? I'm gonna get here, keep his shin trapped, and now my hand goes under his head, my left hand goes under the far armpit. I put my hands together, shoulder pressure, and now my left leg kicks back. And that's your De La Riva guard pass.
