Hope you are not like this at work. The lunchtime canteen can be a lonely place.

	What is GK doing? Sleeping? Running a marathon? Eating a Hawaiian pizza? Thinking up silly questions? Do you know The Golden Condor from Cities of Gold cartoon btw? A wealthy relative?

At the board its easy - Garry will performe, lets say between 2600 and 2851 Elo (it could even happen he makes a patzer 1200 move like Kramnik missing mate in 1), the comp always has 2851. I am not sure you meant it this way - but you cant say the answer was not more serious.

	Of course Garry - a comp may "live" for about 2 or 3 years, a human being for about 70 to 80 years. Its clear that human Garry will consume a lot more energy as long he is in function

	If you compared Garry Kasparov with the most efficient computer running at 2851 ELO, who would use the more energy?
