60: Hansu supported arc-hand strike to one-legged stance

Let's do another Kukkiwon form application.

Hansu is a short but interesting poomsae. In the first diagonal sequence, four puzzling movements are performed. The first is perhaps the easiest to understand. You may use it as a parry while attacking the side of the opponent's jaw (this is why you are at a 45-degree angle), turning the opponent's head.

Next is the twin upset punch, which we use as a takedown. Grab the opponent's ears from behind after turning their head with the jaw strike. Leap forward and pull them down forcefully, throwing the opponent. 

Throw Fails

If the throw fails, the form gives you two options.

The first is if the throw fails but the opponent's head is lowered. We proceed with a simple downward punch to the top of their head. Because we always want to strike through our target, not at our target, we end up punching through where our palm is placed (the palm representing the location of the opponent's head). This has the apperance of being a "target block", but I believe it represents a downward punch.

 

The second option is if the opponent's head is not lowered. We wrap our arm around their head and get a chin lock as we step backwards into the diamond block, restraining the opponent.

For the final move, we can use the one-legged stance as a knee strike to the opponent's coccyx while we pull their head back.
