Day nine of the American Cup in Saint Louis brought the open section to a conclusion, with Wesley So winning the fifth edition of the tournament, while the women’s event remained unresolved after Carissa Yip forced a Grand Final Reset against Alice Lee. In the open, the title was settled without the need for further tiebreaks, as So converted his lead from Tuesday into overall victory. In the women’s section, by contrast, another long day of classical and blitz play still proved insufficient to crown a champion. | Pictured: Wesley So and Maurice Ashley | Photo: Saint Louis Chess Club / Lennart Ootes
