2 Part Technique - Switch to the Deep Half Guard if you lose control over your opponent's head and arm during the a Hook Sweep with Collar & Elbow Control. As you spin underneath, catch his ankle with your hand and wedge your shin into the crook of his knee. Since your opponent can still post in front of his body with his hands, sweep him backwards in the direction that your knee is pointing for the Shin-in Sweep from Deep Half. Use your free leg to act as a pendulum to generate enough momentum to dump your opponent onto the mat. If he shifts his weight forward against the Shin-in Sweep, let go of his ankle and push his body off to the side, allowing you to switch your legs into the 1-Leg X-Guard. Make sure your knees align with his pinched knee and rock his hips back and forth to finish with the 1-Leg X-Guard Sweep.
