Surprised I haven't ran into this yet, but I guess I don't really armbar from guard all that much. Anyway, guy knee on faced me to defend an armbar from guard. Worked really well. I was trying to go over in my head how to prevent this from happening in the first place. Pressure on their face from your leg won't seem to do the trick as I see it in my head, if anything just give them less room to have to travel. I had plenty when this happened anyway. So, tips/tricks/advice? Thanks a lot.
