““Well, of course one must have concentration. Courage. Self-control. That goes without saying. But more important than these, one must have... I don't know how to say it. One must be both a mathematician and a poet. As though poetry were a science; or mathematics an art. One must have an affection for proportion to play Go at all well.Ah... what Go is to philosophers and warriors, chess is to accountants and merchants.””
