Taekwondo Dan-gun Block Strike DrillWe did a drill tonight from Dan-gun against an opposite hand cross punch.
The oncoming punch was deflected using a shuto from the outside (in back stance) - then the leading hand turned into a roundhouse punch that crested over the opponent's arm and shoulder into his face (or side of temple - dependent on position of defender).
The drill helps you think about the flight path, the angle of entry of the strike, and the targetting of where to strike. Is it a flailing blow that is scattered somewhere toward the opponent? No. It 'crests' the shoulder because you know that to just fling the strike will cause you to encounter an obstacle. It crests the shoulder because you know it's easy to target the head, even if you aren't looking directly at it.
I had an incident a few years ago where I was - after a period of injury - stressed by a fighter who was going 'hard at it'. Unfortunately, I sent an overhand punch without sighting it ... and this collided with the fighter's throat. It wasn't a good scene at all - but highlights what happens when you lift your striking arm over the obstacles he presents.
