I would really like to see your Pyung Ahn Ill Soo Shik.
I'm working on that. I filmed the first pyung ahn one-step today, using my brother (who was almost a cho dan when he quite three years ago), but I overexaggerated my techniques too much, mostly to compensate for his loose techniques. I'll probably want to start over again with a better partner. He was pretty good while he was training, but now he's completely out of practice.
Anyway, if you want, I can describe a few of them for you. They start, as usual, with the defender in choon bee stance and the attacker back in a front stance low block.
#1: (a) Attacker throws a front kick with his back leg / Defender steps back into hugul jase with left foot behind and blocks the kick with his/her right hand. (b) Defender hammerfists to the face / attacker blocks hammerfist with right hand high block. (c) Defender steps forward into chungul jase with left foot forward and center punches with left hand / Attacker steps back with right foot into hugul jase and blocks punch with choong dan soo do mahkee. (d) Defender wraps left hand around opponent's left hand (forward in the knife-hand block), grabs, and delivers a right-leg (back leg) ahp chagi to the ribs, then comes down, twisting the opponent's arm as he/she pulls left hand back to ribs and brings right elbow down on attacker's elbow (to break it).
Pretty easy to see where that comes from in pyung ahn cho dan.
#2: (a) Attacker throws a front kick with his back leg / Defender steps back into hugul jase with right foot behind and blocks the kick with his/her left hand. (b) Attacker throws a center punch with his/her right hand / Defender blocks punch aside with a single knife-hand block (c) Defender steps out left foot into chungul jase and reverse-punches to center / Attacker steps back with right foot into hugul jase and outside-inside (open-hand) blocks punch. (d) Defender throws right-foot (back foot) front hook kick to attacker's face / (Attacker steps back to avoid kick)
Again, this follows directly from pyung ahn cho dan.
#3: (a) Attacker steps and center-punches with right hand, then reverse-punches with left-hand, no second step / Defender steps back with right foot into hugul jase and does inside-outside / high block (left / right hand), then outside-inside block with left hand for the second punch. (b) Defender grabs opponent's left arm (had just punched) and uppercuts with right hand (had been in high block position), turning into chungul jase. (c) Defender picks up left foot, pulls back left hand, and turns into keema jase and side center punch / Attacker steps back with right foot into hugul / keema jase and blocks defender's punch downward. (d) Defender wraps hand around attacker's, grabs, steps behind attacker, grabs attacker's dobok near the throat on opponent's left side, pivots and throws opponent to ground, keeping knee on opponent (and pulling to choke).
First part is pyung ahn ee dan verbatim. I'd like something more original for this, especially because I'm blocking in two places at once, but this is a decent starting place. I can always practice my own variants, for my own edification.
That was only three...I'd write out the rest, but it'd be a lot of writing.
