REPORT ON THE 17TH OPEN DUTCH COMPUTER-CHESS CHAMPIONSHIP
Alphen aan den Rijn, The Netherlands
22-23 and 29-30 November 1997
Th. van der Storm
Amsterdam, The Netherlands

For the first time, the annual Dutch Computer-Chess Championship was held in Alphen aan den Rijn, The Netherlands. It was the 17th edition and as usual the organisation was in the hands of the Computer-Chess Association of the Netherlands (CSVN). The tournament was hosted by Broekhuis Pro Training, our new sponsor. The players were welcomed by Saskia Kaaks, the Director of the office in Alpen aan den Rijn.

The titel defender was CILKCHESS 2.0, a program of MIT Laboratory for Computer Science. It was running on a computer located in the USA, with 4 DEC Alpha 466 MHz processors. This was not as fast as their 1996 hardware, but still the fastest among this year's competitors. The games were played in the classrooms of Broekhuis Pro Training, where internet connections and PC monitors were readily available. Most other computers were PCs based on a 166 to 266 MHz processor. The playing tempo was 90 minutes per player for the whole game. There were 16 participating programs which played an 11-round Swiss-system tournament.

In the 7th round NIMZO 98 took the lead when THE KING beat CILKCHESS 2.0. So Johan de Koning had his revenge for last year's defeat even though he now finished at the third place. As always there was a friendly atmosphere in the tournament. In the second weekend the International Masters Herman Grooten and Rob Hartoch provided commentary on the games.

The commercially-available MS Windows95 chess program NIMZO 98 by Chrilly Donninger, Helmut Weigel and Andreas Kure from Austria allowed only two draws, and won the tournament with a score of 10 points out of 11 rounds. The program was running on an Intel Pentium II at 300 MHz. Some years ago Chrilly Donninger lived and worked in The Netherlands, he then adopted "our" computer-chess hobby as his own. Thereafter we saw him and one of his programs in almost all important tournaments. Recently he has quit his job to devote most of his time to computer chess. Therefore he was too busy to come to the Netherlands. Hence, Jan Louwman was so kind to operate NIMZO 98 throughout the tournament.

Thanks to the fact that most participants provided their games on floppy, I was able to put them on my brand new homepage shortly after each round. The URL of "Stormy Chess Corner", where the games can still be found in Portable Game Notation (PGN) and MS Word including diagrams is: http://ourworld.compuserve.com/homepages/thstorm/.

The games of CILKCHESS 2.0 could be monitored live on their own WWW pages. The results of the tournament are given in Table 1. Information on the programs and authors is given in Table 2.

Table 2: Participants of the 17th Dutch Open Computer-Chess Championship.

After the 6th round Remy de Ruysscher  reported that  he accidentally  played the ZARKOV program  instead of his own  SHANNON program. In order to minimise the disturbance to the tournament, the arbiter Rienk Doetjes decided that the  same version of ZARKOV should continue to play on behalf of the organisation, and not for competition.
