Four players representing the United States scored full points in round 5 of the Berlin Grand Prix. Levon Aronian and Hikaru Nakamura both won and are now sharing the lead in pool A, much like Wesley So and Sam Shankland, who are now co-leaders in pool C. Given round-5’s results, we are likely to see tiebreaks after Monday’s final round, as none of the four groups has a sole leader at the moment. | Photos: World Chess
