Ancillary Kebonsu


For each of the basic "core techniques"--"KEBONSU" there is an ancillary technique intended to show a comparitive or contrasting use of the biomechanics. These ancillary techniques are presented here in the same order as the primary YON MU KWAN core techniques. 



Ancillary Technique #1 : Armpit Arm-bar

Drill: The attacker executes straight grab to the wrist. The defender counters with a rising motion, trapping partnerís wrist in the webbing between the thumb and forefinger of the defenderís lead hand from beneath. Defenderís trailing hand arc wide between attacker and defender and traps the partnerís wrist from above in the trailing hands webbing. In a 180 degree pivot about the partnerís wrist the defenderís wrist slides over the partnerís arm, and the partnerís lead elbow is snugly held in the defenderís armpit as rising pressure is applied to the partnerís lead wrist. Emphasis is added with hip pressure induced by collapsing the defenderís knee in the direction of the partnerís shoulder while strongly flexing the partnerís lead wrist towards that same shoulder.

Points to Ponder:

         The focus of this technique is a balance between the stabilizing pressure exerted by the armpit on the elbow joint and the lifting pressure applied at the wrist joint. The dynamics of this motion often invites the defender to compromise his balance to gain additional effect. This is evident in beginners who have not yet grasped the simple effectiveness in accomplishing this technique with equal effort of both the shoulders and the hips.                   



Ancillary Technique #2 : Two-finger Projection

Drill:  Attacker applies cross-hand wrist grab. The defender responds with sharp downward tiger mouth strike to the partnerís wrist simultaneously clearing the defenderís lead hand, and grasping the partnerís wrist. The defenderís cleared lead hand cups the back of the partnerís hand with palm heel aligned with the partnerís first row of knuckles. Pressure on the back of the partnerís hand combined with restraint of wrist induces pain at the wrist joint as it is hyper‑flexed.

Points to Ponder:

        This technique is named for the two-finger placement which is on the end of the forearm, yet, not in support of the partnerís wrist. The wrist should not be encircled with the defenderís entire hand, as this defeats the mechanics of the technique.
