Butterfly Guard Situp -> Choke -> Sweep

B is in my butterfly guard with me flattened out on my back. I extend my legs and sit up. My left arm comes around B's right arm and I for a one arm tie up grabbing his collar. My right arm posts on the ground and I do a technical stand up so my right leg comes up. I keep my left leg with a butterfly hook and bring my right hand into the collar palm up. I then bring my right leg into B's leg so that the top of my foot is on the outside of his leg with my left leg hook on the inside. If B tries to block the choke and posts out their left leg, I use my hook to elevate and sweep them to my right side.
