Side Control -> Mount -> Armbar

Step 1: I start in top side control position on B's right side with an opposite side arm triangle locked up. (B's left arm is trapped)

Step 2: Switch base to clear B's right arm

Step 3: I slide my knee up to B's hip and slide it across to get mount

Step 4: Tracing my right arm along the mat, I switch to a modified S mount

Step 5: I tie up B's left arm by grabbing my own lapel with my left hand

Step 6: If B defends the armbar, I use my right hand to post out towards B's head and turn my hips over towards B's head to break the grip
