Did Deep Blue Ever Win A Chess Tournament Against Gary Kasparov?

After narrowly beating the IBM computer in 1996 in a six game match, the opening game of which was won by Deep Blue, a return match was arranged for the following year. The by then extensively upgraded Deep Blue took the honours 3.5-2.5 over the six game match before being retired by IBM.

Since then Vladimir Kramnik has drawn an eight-game match with the computer program, Deep Fritz. And returning to the fray in 2003, Kasparov drew a six match game with another piece of software, Deep Junior and similarly could not overcome the X3D Fritz program in November of that year, all four games being draws.

Pitting man against machine in the context of chess, though, has been about more than a machine beating a Grandmaster, or rival computer firms vying for the prestige and kudos of being first to crack the challenge. The research and development efforts over the years have brought about a number of innovations, not least the ever more sophisticated computerised chess games that are now commercially available.
