Arno is a chess enthusiast living in Amsterdam, the Netherlands. He started organising and arbitrating chess tournaments at a young age, with a focus on youth tournaments. He has been involved in over forty Dutch youth championships in all kind of categories and disciplines. As inexperienced, young players obviously lead to ‘special’ and delicate situations, Arno knows his way in solving all kind of problems. Later on his interests shifted to arbitrating FIDE rated tournaments, gaining his International Arbiter title in 2014. Next to Altibox Norway Chess in 2015 and 2016, Arno is a regular arbiter at the world’s highest rated open tournament on the Isle of Man. In daily life Arno practices tax law, thus using his experiences in chess arbitrating and law both in his hobby and in professional practice.
