I thought I'd resurrect this thread to point out something I just noticed watching MB videos.
After doing the pass, you're supposed to get back to a belly-down tripod position to put pressure and stabilize the position. But I realized I was doing it the wrong way: if you do what comes naturally and step forward with your back-stepping leg, you're moving *towards* his leg, and walk right into his guard.
Instead you have to do a technical stand-up kind of move and bring your non-back-stepping leg (the one that's flat on the ground) *behind* you and towards the other guy's head, moving away from the guard in the process.
I can't say I'm very good at doing this yet, but if you drill it until it becomes natural, I think it can make a big difference in the success of the pass.
