Chess Variants

Knights Templar playing chess, Libro de los juegos, 1283.

There is a psychological motif underlying the making and playing of boardgames, as explicated in my game alchemy essay. It corresponds to mandala creations, which try to encapsulate the hectic game playing nature of human life. As a whole, constructs such as these are expressions of psychic wholeness, a dynamic form of mandala. They are not meant to be studied and analyzed, because that would be a waste of valuable time. Still, it’s entertaining to play a game or two against my programs. Suffice it to say that this motif, the playing of games, is what underlies practically all human activity, whether in art, politics, science, or technology. Fascinated and obsessed, we play our “games” according to predefined rules; but from a bird’s eye perspective we appear like little laboratory mice running around in labyrinths.
