ok kiddies gather round and listen to uncle alex....
nah but being serious.
in the ring its generally about the positioning of the head. the blove provides a large area, increasing the strike surface and therefore the ffluid shock to the nerves,
in the street its normally the accumiation of punches.

couple of helpers: in the ring, when your sweaty, wipe your gloves on your neck. youll get the surface moist. then wipe the gloves on your shorts when you get a moment, and punch to their eyes.
when you wipe the sweat on your shorts you will leave the surface of the glove damp and grippy, ideal for tearing that tender skin around the eyes!

in the street, punch somone on their right eye. keep punching them in that eye, cause they wont be able to see. ive done this so many times.
just punch people in their eyes, then you can have some fun with them.
not to mention the fact that they wake up in the morning with some almighty shiners... EVERYONE CAN SEE YOUR HANDYWORK
