Dutch Computer Chess Championship

Dutch flagShredder has won the 5th International Dutch Computer Chess Championships 2005 in Leiden, Netherlands and managed to defend the title he has already won last year. It was the first public appearance of the Shredder Macintosh version which will be available this summer here on shredderchess.com. As far as we know this was the first time that a computer chess program running on a Macintosh computer has won a major computer chess event.

Like in the years before I have decided to compete in the event with Shredder, also because Shredder has won the tournament last year and I wanted to defend Shredder's title. Nevertheless things were different this time: as we are currently developing the Shredder version for Apple Macintosh computers I decided to use the Mac version of Shredder in Leiden. This version is not ready for market yet, but it is already possible to play games and as the PowerMacs are also quite fast I decided to give it a try. Here is a quick look at the Mac version of Shredder.

To have a fast computer is crucial in computer chess tournament. Fortunately the Joseph Computer + Service GmbH has kindly offered us a nice Macintosh computer for the event. A dual Power Macintosh G5 with 2.7 GHz,

a very nice and powerful machine. The competition and the schedule were tough like every year. We had to play nine rounds in three days with the time limit of 90 minutes per game for each side. This means that three games a day had to be played and that most of the time was spent in the tournament hall in the Denksportzentrum in Leiden.

Leiden is very close to the North Sea and to Noordwijk and Katwijk, both directly located at the Sea. I have found a nice hotel in Noordwijk close to the beach,

but because of the weather and the tight schedule of the event I wasn't able to spent much time there.

Back to chess: Shredder had a good start on the first day winning against Xinix and Goldbar and drawing the game against Diep. This made Shredder second after the first day after Pro Deo from the Netherlands who was able to win all of his first three games.

The second day was even better. Shredder has won all games against The King, Deep Sjeng and The Baron and as Pro Deo has lost his game against Diep, Shredder was first after the second day with 5.5 points out of 6 games followed by Pro Deo with 5 points.

At the end of day two was the best and only chance to walk around in Noordwijk on the beach front

and to learn some Dutch.

The third day started with the most important game of the tournament: Shredder had to play Pro Deo, formerly well know as Rebel by Ed Schroeder.

It was a very tough and complicated game, but in the end both programs agreed to a draw. For the rest of the tournament Shredder kept his lead by winning against Gandalf and drawing against Ant in the final round.

I was very happy that Shredder has defended his title with 7,5 points out of 9 games in front of Pro Deo with 7 points and Gandalf from Denmark with 5,5 points.

The Macintosh version of Shredder performed very well and as far as I know this was the first time that a chess program running on an Apple Macintosh computer has won a major computer chess tournament. The Macintosh hardware has also proved that it is very competitive and fast.

Shredder for Macintosh will be available this summer here on shredderchess.com. You will always get the latest news about the Mac version of Shredder and Shredder in general here.
