I play GO regularly on the internet at IGS an online GO server. As of this writing I have played more than 1700 games on IGS and I am still only an average player at best. GO is a paradox in it's simplicity to learn and difficulty to master. Which is why so many get hooked on the game. I play GO because of the nature of the conflict, the aesthetics of the game and the mental work out GO provides strategists who daily must contend with opposing ideas.
A while back I literally stumbled across an obscure GO book (it was blocking the aisle at Borders) written by Troy Anderson (with the encouragement of Marketing Godfather Phillip Kotler) titled The Way of Go: 8 Ancient Strategy Secrets for Success in Business and Life.
Troy's an alumnus of Northwestern who's Alumni Magazine published a nice article about his book. One comment Troy made in the interview with the publication was especially enlightening:
Anderson says those who believe that "dominating an opponent" is always appropriate, might be surprised that The Way of Go demonstrates otherwise. "Sometimes the right strategy is to be passive and play your opponent's best move," he says.
