< Prev Next >

The Ninth World Computer Chess Championship took place from June 14 to 19, 1999, at Heinz Nixdorf MuseumsForum, Paderborn, Germany, in conjunction with the Advances in Computer Games 9 conference. The 9th WCCC was the combined 16th World Microcomputer Chess Championship for all participants playing on a microcomputer. The tournament was organized and hosted by the ICCA, the Paderborn University and the Heinz Nixdorf MuseumsForum.

The championship was quite thrilling. After six of seven rounds reigning World Computer Champion Fritz was the sole leader with 5/6. Shredder, Ferret and Junior were following with 4½ and the last round was a real showdown, since Ferret had to play Fritz while Shredder had to play Junior respectively. Ferret and Shredder won their games and were tied for the first place. Shredder had more resistance points, so that Ferret was obligated to win the play-off [1] . After a thrilling game, which ended in a draw, Shredder was the lucky winner of both titles simultaneously.
