Fans of computer chess and those curious to see which engines they "must" buy (because it would be crazy for an amateur to have an engine with a paltry 3120 rating when there's one with a 3157 rating instead) will want to check out the TCEC (Thoresen Chess Engines Competition) here.
At present it's at the semi-final stage, with four engines going at it in a 16 cycle round-robin. Almost halfway through Stockfish has a narrow lead over Komodo and Houdini, with Critter getting beaten to a bloody pulp. The games run continuously, so you can get your chess fix anytime.
