If you know your opponent is much worse than you, then chess can still be fun because you dare to play stupid moves. Open with Nh3 and then continue stupid development (don't leave obvious blunders). Or otherwise don't make your known best move until the game is more even. Or spot your opponent the queen from the start. Lots of ways to even out a game when you are better.

When you are worse though, you have to depend on your opponent doing the above. And then you have to depend on the continuing until finally you are so much better than even you can win.
