22. Koryo low target hammerfist

Source: Majest

Here is an application for the supported elbow strike followed by the low target hammerfist in Koryo.

Assume the opponent grabs your lapel. Use the downward palm to cover and grab their knifehand. Twist their wrist as you bring your elbow over their elbow, creating a Z-lock (aka S-lock or nikkyo). Pushing their wrist towards them will force them downwards.

The Z-lock works by preventing the opponent's elbow from rising as you push their wrist towards them. Since it can't rise, the lock forces them downwards. Step in close and follow with the low target hammerfist to the head.

I used to think that slow motion movements were grappling techniques, but often I see the opposite in forms: normal motion movements can be grappling while slow motion movements can be strikes. Slow motion movements may either be for aesthetics or to indicate that something non-obvious is going on.
