From July 9 to July 18, the 4th Leiden Chess Tournament was held in the Mind Sports Center in Leiden, Netherlands. The event was comprised of two tournaments, the A event, for players rated over 1850 Elo, and the B event, for players under 1900 Elo. Both tournaments were nine rounds played at 40 moves in 90 minutes, plus 30 minutes knockout, with a 30 second increment per move as of the first move.
The A event had 97 players, including five grandmasters, five international masters, and seven FIDE masters vying for the 1750 Euro first prize. GM Erik Van den Doel looked as if he were going to run away with the tournament, with an impressive 6.5/7 start, but two consecutive losses in the final rounds left him with a bittersweet fourth place. First through third were GM Pedrag Nikolic, GM Sergei Tiviakov, and IM Eelke Wiersma, all with 7.0/9.
