Now that Othello is solved, there exist a set of rules a player can follow to guarantee a win or draw every game. It's possible (if unlikely) that a computer could sufficiently compress those rules to be memorizable (and then applicable) by a human.
Say, allowing a purpose designed device, but limited to 1W of power consumption. Or some fixed energy budget (J) per move. Too strong? Take it down to 0.1W, 10mW or whatever.
That would degrade brute forcing as a viable approach, and bring it back to smart algorithms, clever ways to reduce the search space, etc.
From the computer point of view, it's more possible states to explore, so I think it makes things much harder
