I always called it a Duda. It's just an arm crush. Sean Applegate is the man with arm crushes. He knows one from pretty much anywhere..sneaky ones or just your basic from spiderweb. I've gotten hit with this before and have played it myself. I need to get back on tht..I just don't train a lot of arm crushes/calf crushes bc of competing and being a white belt..not usually allowed. But either way a BA move.
