When defending Side Control the first thing to do is keep your arms tight to your body, staying on your side. From here create space by placing your nearside arm on your opponents hip and far side arm across their face. Frame with your outside arm by lifting your wrist. At the same time, push off your opponents hip and shrimp to create space.
Once you have control of the nearside arm, switch your hips to the scarf hold position and pass your top leg over your opponent’s head. Lean back to straighten your opponents arm, finishing the Nearside Armbar.
