And Beyond Rybka?

  • Monty Newborn


As the first decade of the twenty-first century and this book come to an end, Rybka’s reign at the top of the world of chess-playing entities is now four years old. History has shown that staying there for much longer is a tough task. A number of chess engines have risen to the top including Chess 4.0, Kaissa, Belle, Cray Blitz, Hitech, Deep Blue, Fritz, Shredder, Junior, Hydra, Zappa, and now Rybka. All but Hitech and Hydra established their positions at world championships. None but Cray Blitz held the title for more than four years. Cray Blitz did so for six years. However, though champion for the longest time, it was best by the narrowest of margins. Fritz won the title in 1995 and held it for four years until Shredder took it away in 1999. Junior, the comeback kid, captured the title three times, in 2002, 2004, and 2006, each time only to be relieved of it the following year.
