The ancient Chinese game of Go has more possible moves than the number of atoms in the universe. Unlike chess, Go cannot be won using brute-force computing power to analyze a lot of moves — there are just too many possibilities. And, unlike chess, strategies for winning Go cannot be meaningfully codified by rules: its principles are mysterious. In some cultures, Go is seen as a way for humans to connect with the divine via instances of intuition, by “knowing without knowing how you know.”
