A 600 ELO point difference in chess basically means you will never win, and it becomes futile, and crushing.
But after losing a dozen times with that guy, you play against someone else and it's you that crush your opponent, so not so futile.

I do improve playing against better players than me. Like 200 or 300 this year. Maybe it's because I'm more focused when the opponent has a better rating.
