thank you for your very figurative analogues, they are fitting quite well imo. The point you make about chess about having "no room for the slightest error" is also why I never liked it as much as Go (as most westerners, i grew up with chess but then learned Go as adolescent): In Go you are baffled by genius strokes, in chess you are baffled by idiotic strokes (funnily, in both cases it doesn't really matter if it comes from your enemy or yourself). At least that's what my impression is. Opinions may differ :)
