Tried to work some submissions from guard, ended up just playing guard with someone at about 50% trying to get a better feel for openings. I told coach how I was in a bit of a rut, having trouble imposing my game on those I roll with. He showed me a new way to break someone's posture, and talked about the difference between what he called regular chess vs speed chess, in that I needed to take my time and plan ahead rather than just try to throw things in when I see an opening.
He also brought up the importance of keeping pressure on someone in order to lead them into giving an opening, such as pulling on their arm when I actually want to push, because they'll end up resisting in the direction I actually want to go.
New posture break
* If they've got both hands locked in on my hips
* Get both my arms under their arms
* Make a prayer gesture, and lift up
