The 59th Biel International Chess Festival kicks off with the ACCENTUS Chess960 Masters. Six players battle in a round-robin format starting Saturday in Switzerland. Aronian leads a strong field that includes Le, Erdogmus, Bluebaum, Yakubboev, and Alcantara. The rapid format (15 minutes plus 5 seconds) rewards sharp tactical vision over preparation. Chess960 removes opening theory entirely, forcing players to think from move one. Watch for Aronian's adaptability and whether the younger talents can crack the elite competition.
