That was a horrible choke, at least from a martial arts perspective. It was on the windpipe, that is dangerous. A real choke is on the carotid artery on both sides (and much tighter.) Although I’d have to say, it was so weak I doubt any damage could have been done. Did stop the fight though.
Agree. Not a very powerful application of the hold. Done properly, the head is forced forward onto the forearm by the shoulder and the clasping hands draw the forearm further in to compress the windpipe. Gets the opponent’s attention RIGHT NOW.
There is a counter but you have just a few seconds to begin applying it. I do agree it is dangerous as a collapsed windpipe is harder to reverse than a temporary interruption of blood flow to the brain. I believe I have also read that the throat physiology of African Americans makes them more vulnerable to this type of hold.
When I learned the hold in Marine Corps bootcamp these many decades ago, it was called the “naked stranglehold.” (Boot camp was full of colorful descriptive language - most of it describing various sex acts and references to one’s parentage.) I believe the proper name is arm bar chokehold.
