Many chess players visited Delft during the Easter weekend this year to play some interesting chess games. On 29, 30 and 31 March 2013, the sixth OGD Prinsenstad Tournament was organised by OGD and the Delftse SchaakClub (DSC).
The playing venue for this tournament was the auditorium of the Grotius College at Juniusstraat 8 in Delft. This is a new location; unfortunately the previous playing venue is no longer available.
Each game was played with 1:40 hours per person, with an increase of 10 seconds for each move that is played.
Dutch GM Erwin L’Ami took clear first place with 5.5 points. No less than seven players tied with 4.5 points, however, GM Jan Smeets and GM Dimitri Reinderman took second and third places, respectively.
