Why programmers should play Go. A good argument for stretching your thinker in weird and wonderful ways. I’ve played my share of Go over the years, and while I can’t claim to be good at it, I can say that it has changed how I think. The important thing to remember, though, is that the stretching isn’t just a result of learning the game, it’s also the result of thinking about the game, and reflecting on the patterns of play and tactics.
