Question for clean-up:
In the 2nd to the last frame, I would expect the opponent to try to hook the left leg with his free right arm, while stepping up and towards you with his unchecked left foot. Additionally, posting your arm stiffly to the head seems like an invite for him to slip it and sieze the extended forearam, and perhaps even sit-thru to get one of his legs around it for a grapevine arm-bar (if not just to hook your shins to slow your rearward momentum).
So...If he's staying sticky, how do you disengage? Is there a modificaion that allows you to flatten him out first, ostensibly making it harder for him to follow? (i.e., slide the right foot from it's check position at the left hip, down to the knee (blade of foot along the mat; palm of foot over top of knee), and pop it away from you so his leg is forced into hip extension?
Looking forward to reply,
Dave
