Sorry for the thread necromancy, but I took a bit of a shine to Crazy Monkey when I stumbled across this video on dirty boxing in the CMD "straight jacket clinch":
I have seen a few people badmouth this sort of clinch and dirty boxing more generally as being worthless if you know how to work a Thai clinch. But mightn't the straight jacket clinch be more useful if you were fighting someone else who knew how to work a Thai clinch? While dangerous, I always think the Thai clinch leaves you pretty much as exposed as your opponent, and also only works well when you can keep a certain distance; once your hips have closed with your opponent's you can't really work your knees the same, and this is likely to happen in real life if, say, you get pushed up against something, or in MMA if you get pinned/pin someone against the ropes or cage.
The Thai clinch is actually mentioned as part of Crazy Monkey's overall clinching programme too, so one might have thought they wouldn't have bothered with their "straight jacket" stuff at all if the Thai clinch was so great.
