Being to smart would ruin the game.
You’d have two guys able to see thousands of moves in advance.
Stupidity and inability is what makes chess fun. Otherwise you are simply repeating the same moves over and over again, there is no challenge in the least, just a bunch of memorized moves that play out the same everytime.
And then you just throw up your hands and don’t want to play anymore.
Super advanced ability would also ruin basketball games and other games like it. Each and every shot is sure to go in. No one would even watch. It would just go in every time.
However. You can change the point of the game to the opposite goal. The goal could be losing from now on. And that would become an almost unaccomplishable goal to have in such a circumstance. The one who loses is deemed the winner, it’s the only thing that works with super intelligence and super abilities.
It would be so hard to lose a chess match intentionally if both players could think that far ahead and they both had the memory of an entirely advanced computing system.
