Another Pass

Today I saw a pass that fits in well with the passing game I saw this past weekend.  From half-guard, grapevine your opponents leg with your arm on the trapped leg side.  Use forward pressure and then raise your chest while simultaneous using your other hand to rip their knee down, sprawl on top of this now horizontal and collapsed knee. Now using low hips and shoulder pressure on their legs start walking toward your free side and around to control their head and pass.
