computer chess championship

In an exciting last round of the World Computer Chess Championship in Pamplona, Rybka defeated Junior with white to claim another consecutive World Champion title. The strongest computer program at the moment finished with 8,0/9, without losing a single game and having only two draws (against Shredder and Hiarcs)

Junior was supposed to get at least clear second place having in mind computer ELO ratings. Draws with Deep Sjeng and Shredder were logical, but the draw with Equinox (the Italian program at the event) stirred the table. Junior finished with the same points as Shredder and Deep Sjeng and only the tiebreak (Sum of Defeated Opponent Scores) gave Junior the silver.

Hiarcs, running on the same Intel Xeon W5580 @ 3.2GHz x 8 as Junior, finished 5th with 6,0/9. It did well against lower rated opponents, but achieved only 2 draws against the higher placed computers.

Jonny finished a stable 4,5/9 managing to score 4 victories and a valuable draw with Shredder.

The lower part of the table is completed by The Baron, Equinox, Pandix 2009, and Joker.
