It started out as a joke in an Amsterdam art gallery in 2003, but has since flourished into a fully fledged sporting event. A simple concept really – play four minutes of chess, followed by two minutes of boxing. The one who reigns victorious does so either by knockout or checkmate. And don’t forget about the legendary afterparty DJs and special guest cabaret. It’s a night jam-packed with a punch (pun very much intended). Over 18s only. Afterparty until 3am.
