More work from side control tonight.
We started off with the same move from side control to the mount. I felt pretty good with this technique - though I've done a lousy job of integrating it into my sparring so far ... Rodrigo added a very nice, very smooth near-arm armlock to this move that is also something I should practice and implement.
The armlock comes from the same side control-to-mount setup. You've got him all wrapped up. What you want to do from here is to grab the pants with your southmost hand and push his leg away, helping turn him to his side. Then, after subtly hooking your north arm around the top arm (the near arm) that you have bundled up, hop up with your south knee wedged right under the guy's armpit. Pull the guy into you with your hand grips as you push with your knee. Be sure to bring up your north leg on the other side of the arm/shoulder and squeeze your knees as you go for the armlock.
One aspect that Angela pointed out when we were drilling was the importance of getting a very high scarf hold. That is what will make it easier to fold the guy in half, turning him on his side, and getting a good angle for the armlock. The principle is pretty similar to the one in the choke/armlock attack from S-mount.
