To maintain back control in BJJ, fall to your strong side — the side your choking arm is on. That one decision eliminates the shoulder scrape escape and turns a two-on-two hand fight into a two-on-one advantage in your favor.
Most people learn the seat belt grip and then lose the back anyway because they fall the wrong way. "If I fall this way, he can start doing shoulder scrape," Scott explains in the lesson. "If I fall this way on my strong side, it's a whole lot harder. His neck is going against my arm." That's the whole game right there.
Once you're on the strong side, the real work starts. Take the top-hand wrist with your top hand. Push it down to his hip. Hook your leg over his trapped arm. Now he's pinned — literally one of his arms is out of the fight. "How many arms I got? How many arms he got?" Scott asks his student. Two versus one. Nobody wants to fight two on one.
From there, he can't defend the choke properly. If he shoves his chin down, you take your free hand, pull his forehead back, slide your forearm in, and finish with a forearm choke — no full rear naked needed. Works every time you get the wrist trap set clean.
The principle under all of this is dictating position. You chose the fall side. You chose which arm to kill. You chose the choke. He's just reacting. That's what maintaining back control actually looks like — not white-knuckling the seat belt while he bucks and rolls.
