A sort of back to basic question or idea here.
the double punch I feel sometimes gets overlooked a little in the pattern/kata application. After all, it is just a punch done twice.
I think some traditional applications have the meaning as literally 'hit the opponent twice' and I have seen some ideas on applications that have the meaning that you should hit a lot, this is really just saying the same thing. both I feel are erroneous as we have n guarantee that the single punches found throughout the patterns will do enough to incapacitate an attacker, therefore at the end of every technique, we should be ready to hit again.
To look at the double punch I am going to pul a couple of examples:
The way that I apply the sections of the patterns with the double punches all involve grabbing
in Do san, I see what is commonly called wedging block (0:26) as getting off the line and grabbing 2 points, shoulder and arm maybe, kicking legs or knees and then double punch.
in Yul Gok much the same in the opening movements, we have what I interpret as a reap, double punch, followed by an arm and clothing grab, kick to the groin and then double punch.
in all these cases I think that the double punch is giving us a choice. since both hands are busy holding, we choose which one we want o release to punch the opponent. This could be based on the position of the opponent or which even grip you feel is the weaker.
i would love to hear other's thoughts on this.
