Rolling with Clint tonight, I got caught in a triangle choke. It certainly wasn't the first time--not by a long shot. But I forgot a key element (or two) when I was trying to escape.
I went for Mamazinho's standing escape. My big mistake was in grabbing the wrong collar. I grabbed the far collar and then tried to somehow pull it back towards me across Clint's neck. What I want to do instead is to grab the near collar, the collar closest to the side I'm trying to "pass" or escape on and thrust it across the throat. I think I described it as throwing a left or right cross over the chin.
Another mistake--of somewhat lesser importance, but ...--was in not controlling the hips. What I should have done with my free hand (in tonight's case, my left hand) was to pull down on the pants and try to push his hips back to the mat. If I'm doing everything else correctly, then that move will only make things easier.
Also rolled with Tommy. He's still getting his wind back from his time away, but rolling with him is still like climbing into an industrial strength washing machine. He was working some upside down guard tonight and I wanted to try that move BJ Penn does where you stack the guy and take his back. But I couldn't figure out the angle.
Anyway, Tommy caught me some hundred times in about seven or eight minutes. But one key mistake I made that he pointed out had to do with taking the back of a guy in the turtle. I had been doing the reach under to try and control the wrist. But I got sloppy when I couldn't control it. Leaving my hand and arm floating around under there left me open to one of Tommy's wristlocks, which he slapped on me with typical speed. What he pointed out to me afterward is that I should grab the jacket lapel on the far side if I can't get the wrist and pull it in tight. If your hand is against his body, he said, then there isn't the same amount of space that will leave you vulnerable to a wrist lock or other attack.
I'm not doing so well with my half-guard game. It is sort of stalling out. I'm doing a better job of getting small, but I need to get out of there: either with a sweep or a take-the-back. There are a couple of things that are holding me back: a laziness factor, a muscle fatigue factor and a doubt factor ... all of which I need to work on or I'm going to miss opportunities to improve my game at the pace I'd like.
