Martial artists are known for making use of pressure points in a
fight. Whether applying a joint lock or pressing a spot on the body
with a finger, martial practitioners can inflict pain, at will.
They press a spot on the arm, maybe another behind the ear, and their
opponents howl in pain.
For the purpose of this discussion and this martial-arts article
only, a pressure point will be any point on the body, other than a
vulnerable target, that when pressed with a finger, causes pain.
(This modified definition will suit our purpose.)
We could argue that an eyeball or groin is a pressure point. After
all, press your finger into someone's eyeball and you'll get that
yelp of agony.
Still, I am more interested in the almost secret pressure points.
These pressure points are great for:


* Striking with a phoenix eye fist (one raised knuckle) at a
particular spot, possibly to end the fight in one move.
* Pressing a particular point, to control your opponent more after
snapping on a wrist lock. Use the pressure point to move your
opponent....
