R. Vu sends some thoughts on Go vs. chess from Deleuze and Guattari:

Let us take a limited example and compare the war machine and the State apparatus in the context of the theory of games. Let us take chess and Go, from the standpoint of the game pieces, the relations between the pieces and the space involved. Chess is a game of State, or of the court: the emperor of China played it. Chess pieces are coded; they have an internal nature and intrinsic properties from which their movements, situations, and confrontations derive. They have qualities; a knight remains a knight, a pawn a pawn, a bishop a bishop. Each is like a subject of the statement endowed with a relative power, and these relative powers combine in a subject of enunciation, that is, the chess player or the game?s form of interiority. Go pieces, in contrast, are pellets, disks, simple arithmetic units, and have only an anonymous, collective, or third-person function: "It" makes a move. "It" could be a man, a woman, a louse, an elephant. Go pieces are elements of a nonsubjectified machine assemblage with no intrinsic properties, only situational ones. Thus the relations are very different in the two cases. Within their milieu of interiority, chess pieces entertain biunivocal relations with one another, and with the adversary?s pieces: their functioning is structural. On the other hand, a Go piece has only a milieu of exteriority, or extrinsic relations with nebulas or constellations as bordering, encircling, shattering. All by itself, a Go piece can destroy an entire constellation synchronically; a chess piece cannot (or can do so diachronically only). Chess is indeed a war, but an institutionalized, regulated, coded war, with a front, a rear, battles. But what is proper to Go is war without battle lines, with neither confrontation nor retreat, without battles even: pure strategy, whereas chess is a semiology.

If you're uninitiated, you can learn to play Go at the Interactive Way to Go, or here at Sensei's Library; you'd be a fool not to. I'm on the International Go Server using PandaEgg from time to time, though not as often as I would like—email me at gerry@backwardscity.net for my handle.
