I did some pressure point stuff in wrestling.
Digging my knuckles into the top of the hand (opposite the palm) when they hands their hands locked helped break their grip.
Digging my chin into their biceps tendon at the shoulder helped me get their shoulder to the mat for a pin.
Pushing the curve of my forehead into their temple created enough space in a tie up for a duck-under.
Digging my knuckles into their ribs to create space for me to bridge and roll out when I was in my back.
They certainly weren’t moved in and of themselves, but they gave me that extra little bit to get me what I needed.
Then there’s stuff like kidney shots, liver shots, carotid sinus, kneeing the tailbone, charley horse to the outside of the thigh, squeezing the thigh right near the kneecap, etc. that cause more pain than they should for the amount of force applied.
Call them pressure points or whatever else you want. They work. Not all of them are fight enders, but they work.
And of course the famous fight ender.
