Anyone ever use knee on belly chill dog?

I've had friends mount guys and tell the guys to chill out but they are sometimes rewarded by an up punch.  Ever heard of a guy take a guy down and control him with a knee on the belly without doing the nhb Vitor Beltort v Hess reenactment? 


I've heard knee on the belly is preferable because your eyes are harder to poke and it is harder to get soccer kicked by a thug friend.
