As a board member of the Caïssa chess club and a participant in various competitions and tournaments, he has built up an extensive network in the Amsterdam chess world. Jan is known for his enthusiasm and his (often too) offensive playing style, such as his favorite opening, the King's Gambit.

During his student days he focused on poker and since 2022 he has been involved in the world of chess. If white Martin opens 1.d4 by default and if black he defends with 1….c6.

PR coordinator: Joppe Bolderman

Joppe has already organized a few things during his student days, and with the Amsterdam Open he wants to take this experience into the chess world. He learned how the pieces moved as a child, but it wasn't until two years ago when his roommate invited him to play chess that he really became fascinated with the game. He is now a board member of chess club Zwart op Wit and works as a promotion coordinator on the website, social media and of course the promotion of the event. His favorite opening line is the Marshall Attack in Spanish.

Co​ordinator personnel and logistics: Maurice Buzink

Maurice Buzink is the logistics organizer of the Amsterdam Open. As a child he played chess for a while, but stopped before high school, but never really lost the passion for chess. Now as co-founder and chairman of Zwart op Wit, fanatically playing chess again. Maurice's playing style is characterized by liking to play with at least 1 piece behind.

Organizational professional: Marjolein Aarten

Marjolein started playing chess at around 5 years old, but stopped playing at high school and only found her way back to the chess board at a later age. She is the organizational professional for the Amsterdam Chess Open and in daily life she is Executive Producer at the production company KAOS Amsterdam. Every Thursday is her chess-volunteer-day!
