Mir Lock

Key principles

• · Control the opponent's wrist and secure a figure-four grip to create a powerful lever against the shoulder joint.
• · Pin the opponent's elbow tight to your chest or hip to isolate the shoulder and prevent them from straightening the arm to escape.
• · Use your entire body weight and hip pressure rather than arm strength alone to generate the rotational force for the finish.
• · Anticipate the opponent pulling their arm free by clamping your knees or thighs around their trapped arm as a secondary control.
• · Keep your posture low and heavy to prevent the opponent from rolling into you to relieve shoulder pressure.

Execution

1. 1 From combat base or kesa gatame top, identify the opponent's exposed arm (posting hand or underhook attempt) and secure their wrist with your near hand.
2. 2 Thread your far arm under their triceps/elbow and lock a figure-four grip (your hand gripping your own wrist), pinning their elbow tightly against your torso.
3. 3 Shift your weight forward and sprawl your hips low to flatten the opponent and eliminate their ability to bridge or roll.
4. 4 Rotate their wrist toward their back (paint-brush motion) while keeping their elbow clamped, applying torque to the shoulder joint until you get the tap.
5. 5 If they resist by gripping their own belt or gi, walk your hips toward their head to increase the angle and break the defensive grip.
