Biel-Bienne CHESS is a Swiss tournament organizer based in Biel/Bienne, Switzerland. It operates the annual Biel International Chess Festival, hosted at the Congress Center. Over the years, it has become a reference point for elite and open events.

The organization runs the Master Tournament (MTO), a flagship open chess tournament within the festival program. In addition, it delivers multiple FIDE-rated tournaments, plus rapid and blitz side events. Moreover, a central secretariat supports entries, logistics, and player communication throughout the week.

Furthermore, the team works with experienced arbiters to ensure fair play and consistent pairings. As a result, players can focus on classical chess in well-prepared playing conditions. At the same time, bilingual operations help international guests navigate the event smoothly.
