Go (or Wei-ch'i, as it is known in China) is a centuries-old board game popular across Asia. Many have drawn parallels between military successes and the game's complex methods, in which a player encircles, isolates, and captures enemy pieces and geography, but Go also offers lessons for business. This technical note offers a basic description of Go, followed by a collection of business-strategy anecdotes punctuated by comparisons to Go strategies and quotes from Sun Tzu.
