Sociologists are fond of game metaphors. However, such metaphors rarely go beyond casual references to generic games. Yet games are little social systems, and each game offers a distinctive perspective on the relationship between rules and constraints, on the one side, and emergent order, on the other. In this article, we examine three games-chess, go, and (Texas hold 'em) poker-for sociological insights into contested social arenas such as markets, warfare, politics, and the professions. We describe each game's rules and emergent properties, and then offer a brief theorization of the social world through the "lens" of that game. Then we show how a study of the three games advances the sociology of strategy by enriching ideas about skill, position, and strategic dilemma.
