My take- your milage may vary (PLEASE no "That move should be x, y, z...."; the regional and association differences in the anyos are well documented.) I am not trying to explain the form...if you don't know it this will be hard to follow. I am assuming that you may want to use the applications to the other side as well...
Go to the left or right on your opponent, use a basic siniwallii boxing trap to enter and strike. Follow with an inward forearm shot to the opponents brachial/carotid sinus/S-9/side of neck whatever. In the anyo this is shown right arm to left side of opponent's neck.....do whatever works.
Attempt to grab the opponent behind the neck at the base of the skull with the striking hand; pivot on the foot closest to the opponent while directing the opponent to the ground in a spiral fashion. Attempt and intend a 360 pivot, but undertand that you probably wont get it. When it seems like the right time bring your opposite elbow to the guiding palm, sandwiching the head. Pull guiding palm out, strike to the nape of the neck with a hammer-fist (same side that just did the elbow shot strikes down). So, we have an entry, follow-up, take down, and some shots while the opponent is falling...sounds like FMA to me.
