If you love chess but don't like to squabble over the spoils of the game, steer clear of the chess mayhem on Powell and Market and head over to Cafe La Boheme in the Mission. La Boheme's chess-friendly staff makes the cafe a preferable alternative to the Buckingham Palace of chess three BART stops away. Bring your own chess set or use the cafe's chess mats for an impromptu game. La Boheme even offers free wireless for those few minutes between games. Sure, you could pin stars on your lapel and head downtown for a pickup game under the tarps of the pay-to-play champions, but why pretend? Those guys are in a league the rest of us couldn't hang with. No, we just want a game, to sharpen our skills and to provide a spot of camaraderie.
