So I'm not able to go to BJJ for a short while because I am quite busy, but I am wondering if it is possible to fake or lock an armbar from guard and the guy posts/leans on you that you that you can spin your other leg over their head and lock in an armbar from mount. Was just thinking this, I am sure other people have also thought about transitions outside of BJJ while walking or waiting or something. To be more clear, I lock in a regular armbar from guard but its not locked in at the right place and the guy uses his other arm to form a gable grip to help stop me from locking it in. Is it possible/useful that I throw my leg over his neck and then do an armbar from mount except he is facing downward instead of up? Personally thinking again, I think its better used if possible from a triangle as it seems more well suited, but then again, if you have someone in a triangle position, I am guessing you want to stay in it rather than risk him escaping the armbar from mount attempt. Thoughts? If it is possible and is actually used, can someone post a video of it happening?
