Last night we worked escapes from under side control, under mount, and then worked from halfguard.
I paired up with Will who is a larger guy, but not super huge. When I work the escapes correctly they work. When I spaz out they don't pretty simple. I was higher percentage with knee and elbow to half guard than with bridge and roll. His arms were so long that I couldn't trap one well enough to roll him most of the time though I did pull it off when he tried to sub me and got his arms trapped. From side control I'm good at getting back to halfguard but still have trouble moving from halfguard back to full guard.
From on top of mount I can generally stay on top, though Will damn near subbed me from under mount with some kind of papercutter-esque choke. He probably could have pulled it off live, which would have been embarassing...
I improved some at halfguard, I was able to get some sweeps and fight off sub attempts. From halfguard top I learned the importance of keeping double underhooks. With them I was able to hold him down essentially for ever. Without them he escaped within moments.
At the end of class we worked some Butterfly guard, which is something I want to improve and I learned two things. Thing 1 is that I need to keep my head in front of my hips. Thing 2 is that I need to lock my arms higher up on my opponent, right under his shoulders to allow me to trap an arm when he tries to pummel.
Update: I found out Casca Grossa is the weekend after Superslam, so SCREW SUPERSLAM and their ghetto weightclasses. I'm doing CG instead.
