Big fan of them, but like any technique you have to drill them a lot of to do it in a realistic time.
The last couple classes I’ve been able to hit them from various attacks /defenses.
Just tonight in class I was able to set them up from Front Choke defenses. When I raise my arm to break the choke I notice my partners hand is stuck between my shoulder and arm, with pressure already being applied, and I can grab and lock up the wrist in no time. I apply enough pressure to make my partner tap, leaving them standing, but in a real life situation I would prefer to force my opponent to the ground then run for it while they’re getting up.
So far I’ve caught various people utilizing that technique.
