I recently spent a month playing a board game called Diplomacy, and it turned out to be a surprisingly mind-broadening experience. Pretending to be the German Empire before the First World War, exchanging missives all day with the other “great powers” of that time, finalizing troop dispositions before the daily deadline, and then seeing everybody’s moves revealed at once, finding out who lied, who was betrayed, it’s all very dramatic and addictive. It took me a while to realize (rationalize?) why its hold over me was so persistent: it was because it was getting me to grow intellectually as only a few other games have done in my life. Chess taught me to think “a few moves ahead” past the immediate exigencies of any situation. Poker taught me to manage risk when the future is uncertain. Diplomacy is starting to teach me to extend these ideas past the “kiddie pool” of games where you’re playing against coherent opponents. It repeatedly exposes one, like a school of hard knocks, to stable situations that are rendered unstable by the entrance of a new player.
There’s a faint echo of this effect in the chess-like two-player game of Go.
Learning Go, you repeatedly find yourself in situations that seemed stable, where you were holding your own, that are thrown into disarray by distant parts of the board.
