The grueling, thrilling, and unique marathon of elite chess is back. The 59th Biel International Chess Festival is set to take over the Biel Congress Center (Kongresshaus) in Switzerland from July 11 to 24, 2026. For over half a century, Biel has been a sacred ground for chess players. What makes it truly special is its signature Triathlon format, a brutal test of versatility where players must fight across Classical, Rapid, and Blitz disciplines to claim the ultimate crown.

With a mix of legendary icons, reigning champions, and jaw-dropping prodigies, the 2026 edition is shaping up to be an absolute blockbuster. Here is everything you need to know about this summer's chess extravaganza.

Blitz: Win = 1 point | Draw = ½ point | Loss = 0 points
