A Science of Chess ?

Chess is more than a game—it’s a living laboratory for studying strategy, complexity, and intelligence. Today’s engines play far beyond human ability, revealing patterns and ideas once hidden from view. By learning from them, we can search for the game’s universal features—those that define its very structure—and others that illuminate its inner workings as a complex system. This quest continues a vision once expressed by Richard Réti: the dream of a true science of chess.
