2004: Hydra Slews Shredder in Abu Dhabi

  • Monty Newborn


No sooner than the 12th WCCC was over in Israel and Deep Junior had regained the title of World Champion, Hydra took on Shredder in an eight–game match in Abu Dhabi: The Abu Dhabi Computer Challenge. The dates were August 14–24, 2004. Hydra won the match with a very impressive 5.5–2.5 score, winning three games, drawing five and raising the question of which chess engine was really the best. For half a decade, Junior, Fritz, and Shredder took turns at the top. Now, there was a newcomer, possibly the best of all. The following year, Hydra essentially murdered England’s Grandmaster Michael Adams, and its status grew even higher.
