Hey guys, just a quick question. The other day I was rolling with my training partner, and (I can't remember if I was in his full guard, or half guard) I applied a wind choke using my forearms. I put my right arm underneath his head, tucking the back of his neck between my bicep and forearm, I then laid my left forearm over his neck and locked my arms together around his throat, applying light pressure. He was able to escape from the choke after what seemed like only a second or two. From what I've read about this choke, everyone usually says that is very distracting for your opponent, and painful, but isn't very effective, which I found to be quite true. However, my training partner Josh, even though he was able to escape without injury, was complaining about how it hurt, and the legality of it. My question is, do you guys think that I should continue applying it on him, and possibly him applying it on me, so that we can combat it? Or should we just never use it to avoid injury, and also, is it legal in mma fights?
