I started playing Othello (named Reversi) in 1986 on the first version of MS Windows. In 1999 I played my first tournament at the London Mind Sport Olympiad followed a few days later at the Paris EGP.

Since 2014, together with Marcel Sneek, I teach Othello at primary school 'de Burijn' in my city Alkmaar. So much fun.

My Othello highlight? So many highlights when playing Othello but playing WOC 2014 in Thailand and winning in round 8 versus Makoto Suekuni was probably my highlight.
