When you are in a close quarters situation, a powerful technique can be the Close Elbow or “Banana Peel”.
In this situation, you begin by stiff-arming your threat in the shoulder, creating pressure. If your threat leans back into you, then counter pressure is created. Two forces pushing against each other.
Once pressure and counter pressure has been established, slide your hand off the shoulder, like it slipped on a banana peel. The release of pressure will make your opponent fall forward.
Strike with the point of your elbow to the chin. This can deliver incredible force in a close quarters situation.
