I got into a bit of a scrap a couple weeks ago outside of a bar. i had him in a headlock with his torso in front of me. I just started pulling my left forearm into his throat as hard as i could with my right hand. is there anything else to it? i ended up just letting him go after 10 seconds or so and it got broken up, no real damage done. secondly, what would happen if you held the choke for long enough? does it restrict blood flow to the head? Would he just pass out?
