As the new championship approaches, it’s worth looking back at the 2025 World Diving Chess Championship from the Mind Sports Olympiad.

Zyon Kollen took the title with a dominant performance, while Josephine Damen won the women’s event.

If you haven’t seen it yet, last year’s edition is definitely worth checking out.
