Right hook

The classic is a broken nose and a black eye, but a good punch goes anywhere.

If it's on the stomach, could lead to kneeling, for example.

May be a complementary trope to beaten up, fight or abuse (in which case, will be considered here the relevance of the punch during the fight or such), as well as a case on its own.
