if you have his left leg on your right shoulder:
1. squeeze and straighten your lockdown
2. travel completely onto your left hip
3. gable grip your hands just above his left knee
4. think "put my right shoulder on the mat"
5. put front of your left shoulder on the mat
most importantly, don't overcommit to the sub. if you find that he is too flexible to submit here, just take the sweep. that's still a small victory. beyond that, his resistance to the sub will inevitably leave him open for you to swim your left arm through the 5-hole and find yourself in Stoner Control. look for the Vaporizer finish from here.
