This is for The Sensei, Bagatha, Damian, TKD Warrior, Marginal, Fissure and anyone else interested.
I inquired about the description of some basic moves in Won-Hyo to make sure semantics / names weren't obscuring the verbal description for me. The ITF name for Inner Forearm Circular Block is called an Inward Forearm Block in my system / school (WTF). This difference in names, for the same block, could have caused me to assume you were speaking of something else. I don't like to assume and I apologize for not being familiar with your set of terminology. If my inquiries were out of line somehow, again my apologies.
It is my understanding that preceding the step leading to move 19 draws the feet in close proximity of each other sometimes called natural or walking stance in some systems. Initiating any techniques from this stance in hyung, tul, etc. is really good training for mimicing being relaxed in everyday life and not in a ready battle position. Training to respond to an attack when not prepared stance wise. This makes sense in the form when thinking of it as punctuation between attackers. I don't see this much at all in my forms and it strikes me as very good practice for real life. What I am saying is most problems arise when not in a fighting stance outside the Do Jang. I kind of like this concept myself.
The sequence The Sensei asked about is a defense against a right arm pull / grab to your left arm mainly at the wrist area. Rather than meeting force w/force the left foot steps with / towards the attackers energy. The defenders left hand pulls back at their own wrist while the rotating knife hand edge goes around the thumb side of their wrist and the hand then grabs their wrist / forearm while breaking the attackers initial grasp. The thumb can be pressed into Pericardium 6 to secure a firm hold. Doing all this rotates the attackers arm so that their elbow points down and palm up if continuing a chambering motion to your hip. The blocking arm is then brought up with the thumb knuckle inner wrist bone area as a striking / pressing /raking tool to the attackers elbow area. If you go above your own elbow about one thumbs width, you will find triple heater 10 at the triceps attachment to the elbow. The lateral sideways raking of this point will cause the arm to straighten somewhat and should be held momentarily to control the attacker for the front snap kick to their Liver 13 point at the 11th rib area. A strike to this area, in general, hits the liver or spleen directly. The temporary securing of the arm while kicking to this area increases the likelihood for internal organ damage much like impact increases with two objects traveling towards each other. Once the kicking foot is returning, the grip on the attackers wrist is released and the right arm continues it's blocking trajectory while pressed against the attackers arm effectively sweeping it across his centerline, across the front of his body and aside. This serves two main purposes. First it turns his torso CCW and causes not just his right arm to be cleared from immediately reattacking, but, it also turns his left hand and left hip / leg away preventing an immediate kick from that leg. The right leg is where he will be placing most of his weight momentarily due to his hips reflexing backward so good chance of no immediate kick threat there either. Second the target/s for the punch are now wide open momentarily. That chambered left hand, which released his right arm so it could be swept away, is now slammed in reverse punch fashion as your body falls forward from the right front snap kick. The point spleen 21, which is also just around the back of Liver 13 still on rib 11, can be fully exploited. It is about halfway between the armpit and hip bone. A good old fashioned blow to the kidney will work just as well if he is really turned by the block. If all this makes solid contact and he is still standing I myself would run!
I posted earlier on this thread on the kick punch mehanics and they gel nicely with this apps. explanation. I have very similar moves in my Pal Gae hyung. We have more in common with ITF hyung than maybe first thought.
The position of forms being impractical is both true and untrue depending on their usage and understanding. I understand more in a general sense where some of you were coming from. If I stopped at just thinking there was only a punch or kick coming at me on this series of moves, I would definately be on the near useless side of the fence too. When Damian mentioned the necessity of having a live partner to practice with or the deeper apps. aren't much better, that too I agree with. But, I feel that once having done so, the solo practice is more enhanced and then more constructive.
If you are tempted to ignore or discard my explanation, due to my prior poor attempts at humor, I understand. For those of you that try this, please don't think me rude or condescending for suggesting caution for your training partner. That is a very powerful form you guys have. I'm impressed.
Bagatha, if you look at the sparring against punchers thread, and read my explanation, you will notice how much this Won-Hyo forms app. has in common with my sparring tactics. If you make it hard for your opponent to use all of his weapons by crossing up his stance, he has a harder time dealing with your assault and delvering his. When your Instructor mentioned how forms help sparring, maybe he is meaning on a positional level? Just a thought.
