Overbetting your monsters on river against an opponement you know has a hand he likes is something i HIGHLY recommend to everyone. I think its the greatest part of my game. Its not rare im going to bet like 5x the pot the river if i know my hand is very difficult to read(for example JT on 9QK board) and i am confident i will get called.

Overbetting draws can be good but i won't elaborate since rondavu already did a nice reply.
