Speaking of chess, there's quite the interesting match going on on the Internet right now -- Kasparov is playing the rest of the world (or at least those of us on the Internet who care to participate). Every other day at noon, Kasparov, as White, makes a move. Between then and 6am the following day, you can vote on what Black should do next. Grand Masters have been covering the game from the beginning and recommending moves. Right now, Black's choice is pretty obvious -- it's the middle of a queen exchange.
