The 10th International Computer Chess Tournament took place in Leiden 28th-30th May 2010. Organised by the CSVN, the Dutch Computer Chess Federation, are important meetings for chess programmers to improve their programs. This year, the 10th ICT was played in the Denksportcentrum in Leiden, The Netherlands with 14 programs. A nice mixture of top chess programs like Rybka, Hiarcs, Shredder and Junior and amateur programs like Pandix, The Baron, Spark and Kallisto.

Rybka again took clear first with 8/9.

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 8 points out of 9 games. Rybka lost only one game, against number 2 Deep Sjeng by Gian-Carlo Pascutto. The Belgian program played a fine tournament and scored 7 points. Two programs shared the last spot on the winner’s podium: Hiarcs by Mark Uniacke and Shredder by Stefan Meyer-Kahlen. Both programs scored 6 points. Rybka won the “Theo van der Storm” trophy, named after the late CSVN secretary and organizer Theo van der Storm.

An international tournament it was: we had participants from nine countries: Holland, Germany, UK, Hungary, Brazil, USA, Poland, Belgium and Israel.

Computer chess still attracts many (new) programmers. Last year only eight programs came to play the ICT, but this year no less than 14 (!) professionals and amateurs came to Leiden, 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.

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 next major computer chess tournament will be the ICGA 18th world computer chess championship in Kanazawa, Japan from September 24th till October 2nd. You can find more info on In November the Dutch Computer Chess Federation (CSVN) will celebrate its 30th anniversary of the Dutch Open Championship. The exact dates will be announced soon. Please check for information about the Dutch Open and the other activities of the CSVN. On the website you can also see many pictures of the ICT 10 tournament and you can download all the games.

On Saturday a side-event was played for owners of dedicated chess computers. Ruud Martin won this tournament with a Revelation Rebel 5. We would like to take the opportunity to thank tournament director/webmaster Jan Krabbenbos and arbiter Rienk Doetjes for organizing another trouble-free tournament.
