For those who've never played it, it requires an odd number of players, usually 3 (more is hard to keep track of). Each player takes turns successively, but each turn you're the opposite color because of the odd number. For example, if we had 3 players, (we'll call them Jesus, Buddha and Thor), it would go like follows:
Jesus plays a black stone
Buddha plays white
Thor plays black
Jesus plays white
Buddha plays black
Thor plays white
(repeat until game is over)
Since you play for both teams, nobody really wins or loses, but it's an interesting exercise. You end up having to think up plans that you, yourself don't know how to respond to, which encourages experimental play. It's also a great form of go to play while drinking.
I played this with a couple friends of mine who were quite a bit lower ranked. Eventually one side was in a completely lost position. At that point, I took that side as a "handicap", while they took the other and collaborated on their moves. (I managed to just claw myself back to victory.)
