In 1997, the Chicago Tribune mistakenly reported that Deep Blue had been sold to United Airlines, a confusion based upon its physical resemblance to IBM's mainstream RS6000/SP2 systems. In 1995, a Deep Blue prototype played in the eighth World Computer Chess Championship, playing Wchess to a draw before ultimately losing to Fritz in round five, despite playing as White. Īfter Deep Thought's two-game 1989 loss to Kasparov, IBM held a contest to rename the chess machine: the winning name was "Deep Blue," submitted by Peter Fitzhugh Brown, was a play on IBM's nickname, "Big Blue." After a scaled-down version of Deep Blue played Grandmaster Joel Benjamin, Hsu and Campbell decided that Benjamin was the expert they were looking for to help develop Deep Blue's opening book, so hired him to assist with the preparations for Deep Blue's matches against Garry Kasparov. Jerry Brody, a long-time employee of IBM Research, subsequently joined the team in 1990. Their colleague Thomas Anantharaman briefly joined them at IBM before leaving for the finance industry and being replaced by programmer Arthur Joseph Hoane. After receiving his doctorate in 1989, Hsu and Murray Campbell joined IBM Research to continue their project to build a machine that could defeat a world chess champion. The machine won the World Computer Chess Championship in 1987 and Hsu and his team followed up with a successor, Deep Thought, in 1988. The endgame database contains special scenario for plays with six or less pieces.While a doctoral student at Carnegie Mellon University, Feng-hsiung Hsu began development of a chess-playing supercomputer under the name ChipTest. ~~~~~~~ -Extended book included some specific openings against Kasparov, but they were apparently not used in any of the matches. ~~~~~~~ -However, most of the time Deep Blue works independent of those databases and just uses them as additional input in its decision making process.
