The following footage shows me sharing some details in the application of the joint lock in a posture commonly called “Play Guitar”. Application makes it difficult to turn the limb into the correct position. The forearm has two bones that I can smear between my fingers and palms causing them to turn over and unscrew. This is applied by the turning of my waist pushing one hand forward and pulling the other back. The one turn becomes the two energies. The unscrewing action causes your partners arm to twist his body and present his palm so that you may push or strike the palm using his straightened arm like a pool cue to strike at his head. The result of this can be to launch your opponent away. You can however snatch them back and make them have a head on collision with the posture “Brush the Knee and Twist Step ” … Just like in the form.
