This last bit is a new addition to my game. I learned it from Leo at the Marcelo seminar and saw Marcelo use it several times in sparring. It starts with the same knee drive that we use to go to s-mount, but it attacks them in an entirely different way and unique way.
Again, this is a two parter. The second half of this addresses a common problem with many omoplata setups, where your bottom leg gets trapped under them and you can't turn out for it. This is how Marcelo handles that.
Let's get started and you'll see what I mean.
I have a vanilla mount on Trog. He has his arms in fairly good posture.
I slide my left hand under his right forearm. This is easy to do since no one thinks to defend it. They are waiting for something more obviously like pushing their forearm down for an americana or trying to cross their arm for an armbar.
I drive my arm through until my elbow touches the mat.
Then with one solid slide forward, I drive my left knee up under their arm. At the same time, I bring my left arm back and pinch my elbow to my ribs and grabbing their shoulder, trapping their arm.
Keeping their arm securely trapped, I step up with my left leg.
Alternate angle. You can see how I am pinning their arm in place with my mine. I am also pressuring in with me knee to turn them on their side somewhat.
The key is that I get their arm deeply wrapped around my hip at this point.
