While taking photos of techniques this weekend, I took a shot that didn't fit into the flow of the instruction, but I think it's an interesting enough point to bring up.
I've seen and been taught many ways of controlling the opponent while going for an omoplata. The most common I see is to grab the belt. Hug the knee/thigh. Or Eddie's jewclaw, hugging behind both thighs.
They've all worked okay for me but lately I've been doing this, after seeing my instructor do it a lot and having him show it to me:
I am grabbing the end of the pant leg and straightening my arm to stretch it up and away.
If they try to lift their leg and step over me, I just keep shoving their leg up and away, stretching it out. Every time I do this, they are forced to go flatter and flatter, taking away their base.
If they try to roll forward, I just keep stretching their leg back and away, and they can't roll.
As I do this, I keep scooting my hips away and making my legs heavy and stiff to pressure their shoulder down.
Once I feel I've got them broken down enough (no posture, almost on their belly, shoulder on the floor), I'll sit up and start grabbing the belt, climbing up the back and getting a haress grip. Then I arrange my legs and sit up and forward to finish.
Enjoy.
