The '''21st''' Dutch Open Computer Chess Championship took place at [http://www.denksportcentrumleiden.nl/ Denksportcentrum] [https://en.wikipedia.org/wiki/Leiden Leiden]. It was an eleven round [https://en.wikipedia.org/wiki/Swiss-system_tournament swiss tournament] at two consecutive week ends, October 27-28 and November 3-4, [[Timeline#2001|2001]]. [[Chess Tiger]] was the winner with 9/11, since [[Rebel]] also with 9/11 had less sum of opponent scores, also due to playing [[EEC]] in the last round. A clear symptom the swiss system was a bit degenerated with eleven rounds for sixteen participants, despite most were happy playing so many games.
