Because Deep Blue had no background as a chess player, Kasparov was unable to prepare for this match as he did for other matches in studying the games previously played by his opponent. Levinson and his colleagues at the University of California, Santa Cruz, developed a computer program, called Morph, that taught how to play chess by starting only with a list of legal moves. That a computer that relies largely on quickly checking the consequences of billions of possible moves could come so close to the human capabilities required to play the game at its highest level was a striking achievement for the team that designed, built and programmed Deep.
