This book investigates cultural influences of competitive sports on U.S. and Chinese strategic thinking and tactical behavior. Most competitive sports owe their origins to human fighting. Although they are “ritualized contests,” competitive sports have retained many aspects of human warfare, especially the use of strategy and tactics that moves human contest beyond military clashes to the subjugation of opponents without bloodshed. Cultural influences usually go unnoticed. Indeed, Washington often conducts foreign affairs like football games without knowing that is the case. Likewise, Beijing moves in Weiqi style subconsciously. This book uncovers these influences.
