The algorithms involved are so complex that they have been a measuring stone for artificial intelligence over the years.
Additionally, the game is a (not so veiled) metaphor for battle. King versus King. Black versus white. Good versus evil. At the base level, me versus you.
Yoko Ono’s 1966 “Play it by Trust” set turns traditional chess on its end, in ways both computational and philosophical, with a simple twist.
In it, both sides play white. Are white. Are indistinguishable from one another. As are the squares on the checkerboard.
With this set, the mental calculation necessary to play a good game includes the additional layer of remembering which pieces are yours, and which belong to your opponent.
Says the artist:
Play it for as long as you can remember
who is your opponent and
who is your own self.
How sustainable is battle against an enemy that looks just like you?
How relatively easy is war against a culture that does not look like you?
With not more than a humble color change, this design becomes provocative art.
