Round 4 of the Jönköping Chess Festival 2026 is underway at Scandic Elmia. Rasti, Vernersson, Berggren Torell, and Wenzel battle in this seven-round Swiss with 90 minutes plus 30 seconds per move. The Standard Open format rewards consistency over brilliance, making position play king. Three rounds remain after today. Watch for fatigue to set in as players grind through middle-distance chess.
