30. Eui-Am 5 move set

It's my belief that the five move set from Eui-Am encodes two follow up techniques after using the wedging block against an attack. The set is:

• Front stance knifehand wedging block
• In place, open-handed circular block 
• Bring front foot back into cat stance twin palm downward block
• Shift front foot into back stance reverse punch
• Slide backwards into back stance low inward ridgehand block, bringing back arm into chest

The first technique will use an unconventional application of the circular block: an arm lock:

Block a left handed attack with your right leg forward. Use the long arc of the circular block to wrap over the opponent's elbow while you pull their forearm down with your reaction hand. Doing this with enough pressure will injure the opponent's shoulder.

The finishing move the form provides is the cat stance twin palm downward block. Because this lock forces the opponent to lean left, the cat stance is probably meant to trap their left leg. You may then use your two palms to push the opponent's face to the floor.

For the next technique we will still utilize the wedging block with the right leg forward, but this time against a right handed attack. From this position, our right hand is pushing on the opponent's neck. Grab their head and pull it downwards (pulling hand) while you either grab or underhook their right arm (reverse punch). We finish with a puter kepala throw, also known as "the clock" takedown. This is performed by sliding backwards while pulling the opponent's arm and pushing their head in.

Eui-Am is noteworthy for being the first of the "new" forms, not one of the original 20. Some ITF-schools do not teach these forms, for fear that they were made to be challenging to perform and do not have the self-defense value the original 20 do. But I find the movements in these forms have both applications and a logical arrangement behind them.
