Computer Chess – Rybka wins ICT10 in Leiden
By Eric van Reem
Another title for Rybka! In the 10th edition of the International Computer
Chess Tournament (ICT10) the latest Rybka version by Vasik Rajlich scored eight
points out of nine games. Rybka lost only one game, against number two Deep
Sjeng by Gian-Carlo Pascutto. The Belgian program played a fine tournament and
scored seven points. Two programs shared the third spot on the winner’s podium:
Hiarcs by Mark Uniacke and Shredder by Stefan Meyer-Kahlen. Both programs scored
six points. Rybka won the “Theo van der Storm” trophy, named after the late
CSVN secretary and organizer Theo van der Storm.
On the table below you can see the final results. Remarkable: only 13 of 63
games ended in a draw! Note that both Rybka and Sjeng played on 128 core
clusters; Junior and Hiarcs each had 12 cores, Shredder had eight.
Final table

It was an international tournament, with participants from nine countries:
Holland, Germany, UK, Hungary, Brazil, USA, Poland, Belgium and Israel.

Visitors watching the games at the 10th ICT in Leiden, Holland
Computer chess still attracts many (new) programmers. Last year only eight
programs came to play the ICT, but this year there were no less than 14 (!)
professionals and amateurs in Leiden. They were there not only to play the games,
but also to discuss chess in general and chess programming in particular. These
lively discussions often inspire programmers to improve their engines.

American computer chess and games programmer Don Dailey
It was also nice to some new faces in Leiden, like special guest Don Dailey.
He is an American computer games and chess researcher and programmer. Dailey
is author of various computer chess programs starting in the 80s. He played
in Leiden with his latest program Komodo.
A newbie in Leiden was the Brazilian with the remarkable name Ben-Hur Carlos
Vieira Langoni Junior. He debuted with his program Red Queen. He started working
on his chess program just one year ago and promised to come back again! Hopefully
he will score more than 0.5 point next time.

The winners: Gian-Carlo Pascutto (programmer DeepSjeng), Hans van der Zijden
(operator Rybka), Harvey Williamson (operator Hiarcs) and Ernst Walet (operator
Shredder)
