Shredder 9.0 wins the Copa Mercosur

VIII Magistral de la República Argentina

Copa Mercosur – Torneo Internacional de Ajedrez

The event took place from July 14 to 25, 2005 in the Circulo Medico de Vicente López, Buenos Aires. There were two closed round robin sections (and a big open). In the closed sections the computer program Shredder 9.0, running on a PIV, 3.5 GHz, with 512 MB of RAM, was participating, as it traditionally does evey year.

Shredder 9.0 playing in Argentina

First prize to the top human player Andres Rodriguez of Uruguay

In the final table of the Mercosur Cup Shredder 9.0 has been assigned an arbitrary rating of 2600. As we reported the program committed an inexplicable blunder in round three, giving up a whole piece for nothing. We can only assume there was some kind of technical glitch. In spite of this Shredder finished a point and a half ahead of the best human player, and displayed a rating performance of 2758. Slowly we have to admit: homo sapiens is not playing in the same league as computers.
