1. The attacker's left arm encircles the opponent's neck, with the opponent's trachea at the crook of the elbow.
  2. The attacker's left hand then grasps his own upper right arm [biceps].
  3. The right hand is placed behind (or occasionally on top of) the opponent's head.
  4. The elbows are then brought together such that lateral pressure, from the biceps and radius bone, is applied to the neck on both sides.
  5. Sometimes the attacker's legs are placed inside of the victim's legs and moves her legs out, placing her shins behind the victim's knees, essentially using her shins and feet as hooks to control the victim's legs.
