The Team - Who is who?

Jan is a versatile individual with a passion for chess. He serves as Chairman of the Amsterdam Chess Open and is a lecturer in Commercial Economics at the Amsterdam University of Applied Sciences. As a board member of the chess club Caïssa and an active participant in various leagues and tournaments, he has built an extensive network within the Amsterdam chess community. Jan is well known for his enthusiasm and his often overly aggressive playing style.

Marjolein started playing chess around the age of five. Although she briefly stepped away from the game during secondary school, she found her way back to the chessboard later in life. She is executive producer and treasurer of the Amsterdam Chess Open Foundation and works as a freelance Executive Producer for various clients & brands in the film & photography industry. You can also find her as a curator at the Max Euwe Centre, and every Thursday evening she is active as a youth leader at her club Amsterdam West. In addition, Marjolein plays chess at two clubs: Amsterdam West and Zwart op Wit. She opens her games quietly, but effortlessly switches to an aggressive playing style.

Peter Doggers is an international chess journalist, known from ChessVibes, Chess.com and his book “De Schaakrevolutie”. He is responsible for the PR and communication around the tournament.

Yali loves chess, techno, and soil science. You can find her at the university, in the club working as an awareness officer, behind the DJ booth, or at the chessboard. After learning to play chess on Valentine's Day in 2021, it was love at first sight. Since then, she has organized chess meetups, events, and tournaments. Despite her great love for chess, she sometimes gets a little sad when she's losing too many games—and that's perfectly okay!

I started late with chess, around my 30th year and I got the virus instantly. Meanwhile I have lots of time to play nice chess tournaments also abroad, combining this with holidays. I answer the mails that are sent by the participants.

My name is Rinus van de Krol and I am 64 years old, married, father of two kids and live in Hoorn. In daily life I work at Rijkswaterstaat in a control function, but primarily active for the workers council of the company. Next to being a chess arbiter, I spend time on my family, table tennis, reading, puzzlers and motor cycling.

Serious chessplayer, organiser and material manager, but not that serious.
