Magnus for example talks about the importance of purposely making a sub-optimal move as a way to bluff your opponent. Your opponent likely has memorized all the optimal moves and so you make a sub-optimal move to leave your opponent guessing whether you made a genuine mistake that you can be punished for, or whether you made that sub-optimal move on purpose because you studied it extensively whereas your opponent has not and you know if your opponent doesn't play it absolutely perfectly you can trap them.

It's fun and fascinating.
