So, if you can put somebody down with a strike to the liver or solar plexus, why shouldn't a sudden pressure with a pointed elbow to these point where you put on force and bodyweight due to leverage from a crossover grip manage to open up the guard a bit so you can pass? I have made it hundred of times throughout the years also against decent BJJ practitioners.
I think you are onto something.
Using pointed elbow to open the guard of decent BJJ practioners.
