  1. 01

    From half guard, underhook the opponent's near leg at the ankle and draw it across your centerline, walking your hips perpendicular to align your spine with their shin.

  2. 02

    Thread your near leg over the opponent's captured leg and lock your foot behind your own knee, forming a figure-four that seats their ankle high in your armpit rather than your fist.

  3. 03

    Pin the opponent's knee flat to the mat with your chest and forearm, ensuring the joint cannot travel with the hips when pressure is applied.

  4. 04

    Cup your own hands together over the shin, elbows drawn tight to the ribs, and settle your weight so the opponent's leg is fully suspended and cannot bend for relief.

  5. 05Precision point

    Rotate your hips away from the pinned knee while keeping the shin locked to your chest, turning the ankle against the stationary knee rather than pulling the heel.

  6. 06

    Extend slightly through the hips to finish, applying steady rotational pressure until submission or the tap is given, never a sharp jerk.
