Good day for some standing guillotines.
I grab the back of their head with my right arm, in order to break their posture down. I control their right arm with my left, grabbing their arm around where their elbow is, controlling it back. I posture the top of my head into their neck, as to avoid a possible bite, as well as pushing them back. When they resist being pushed back, I snap their head down and to the left, under my left arm. My left arm comes up under their chin while I grab my left wrist with my right hand. I posture down to create more base, while lifting my left arm up into their neck. This is the Guillotine ?.
The defence is, when I am in a Guillotine, with the arm on their body side free, I swing it up and over their body, coming down their back along side their head. I drop my weight onto them through my arm. I block their hip with my other free hand. To avoid them pulling guard. I move my body around theirs, backing away from the side my head is on. This allows me to get a leg behind their leg, and sweep them to the ground. From here I want to dig my shoulder into their neck, putting my weight through the shoulder, with my weight up onto my toes. With the arm which is not cross facing them, I can then peel the guillotine off, and rotate my chest and head up to the sky.
