In UFC 1 Royce "fought" a boxer.
The boxer's strategy was to wear a glove on his jabbing hand so he didn't hurt his bare fist with all the jabs he would land.
Royce closes the gap and gets the boxer to the mat and then mounts.
The boxer taps before Royce applies a lock or choke.
If you achieve the Mount and can stay there the man on the bottom is beaten even before you make him submit.
