The event was usually played as a mini-tournament in a double round-robin of four top players from the absolute world elite with the exception of the fifth edition in 1991 and the tenth edition in 1996 inviting ten players in a single round robin.
In addition, there was later a moderate strong and independent "Euwe Stimulans" tournament, played at Arnhem in 2007, Amon Simutowe from Zambia won, completing his final GM norm in the process to become a chess grandmaster.
Also at that event, which had a line-up of ten players, Fridrik Olafsson played a famous game against Vincent Rothuis.
Zhao Zong Yuan and Gilberto Milos were shared winners, ahead of clear third John van der Wiel.
Aside from various events (i.e. simultaneous exhibitions), a men's and a women's four-player double round robin was held which was won by (then 13-time Dutch Women's Champion) Zhaoqin Peng in Group 1, while Robin van Kampen took the honours in Group 2.
