Begged off class tonight due to a persistant and ahem inconsistently productive cough. I'm doing "tape work" instead, watching 101 Submissions: Chapter 2 and being blown away by what you can learn about defending against even the world's greatest triangle chokes.
Not a single one of the fighters who tapped out to triangle chokes on the DVD used the counter that Rodrigo showed us. Not only did they not attempt the counter, but also they all made the same mistake.
The mistake? Bringing up the opposite (i.e., non-trapped side) leg in an attempt to lessen the choke.
Kneeing up on the opposite side actually makes the choke worse. All you are doing is driving your body deeper into your arm. By kneeing up on the trapped side instead, you begin to wedge your body between your head and your arm. Kneeing up on the trapped side is not enough. The triangle is an excellent choking attack. But kneeing up on the trapped side is fundamental. And the tape proved it.
What is nice about this counter--which I've called the peppermill--is that there is usually plenty of time to stop, focus on the trapped side and make a determination to take the fight into the trap instead of away from it. That is what all stacking is about.
I should add that grabbing the pants with the free hand is very important to keep the guy from turning with you as you move, knee first, toward the trapped side. You are working as if to pass his guard, stacking on the other knee and grinding with the advance knee, staying very tight.
Deep thoughts ...
If he is controlling your body, free your body
Attack what is nearer to your body than his
Use your legs to fight his body, not your arms
If he attacks your legs, defend with your hips
If he is choking your neck, attack his arms
If he shortens his arms, pin them against his body
