Backbytes - An ill-matched couple

Forget Apollo Creed against Rocky Balboa. This year's big rematch is between chess supremo Garry Kasparov (5ft 10in) and IBM's Deep Blue supercomputer (6ft 5in). Or so Orso, an IBM Netherlands Web site, joyously informs us.

For anyone else collecting pointless human-computer comparisons, here are more. Kasparov: weight: 176lbs; age: 32; neurons: 50 billion; moves per second: 2. Deep Blue: weight 1.4 tons; age: 8; chips: 32; moves per second: 200 million.
