Wow, all that wall of text of digression. Now to the training part of the night, was:
1. Control the head.
2. Grab a hold of the wrist.
3. Get a key-lock.
4. Get a chicken wing.
Option A: Use wing to roll opponent so that they end up in a triangle pin.
Option B: Use wing to roll opponent the other way, pivoting ending in a cross body hold.
The chicken wing was highly effective, although it's effectiveness is determined by control of the head. If you lose control of the head then you lose the technique and they can simply (gasp) sit up, and the position is reversed, and they have your arm and shoulder. So as always, control the head, and the body follows.
Funny thing, today after I was reading this, I read the Growing Judo 2009 August Issue, and well, that was the technique of the month. Actually the USJA publication actually explains it better with pictures! Take a look it starts at page 5.
That's about it, the rest of the night was spent doing randori both newaza and stand up. I have to work on placement of my feet and balance, as I was horribly prone to foot sweeps. UGGH.
