18-year-old American grandmaster Awonder Liang collected 3½ points in Saturday’s four rounds to climb to sole first place at the Kramnik Challenge for young stars. Former co-leader Nodirbek Abdusattorov stumbled against Zhu Jhiner and now stands a full point behind, while Vincent Keymer kept up the pace and also scored 3½ points on the third day action — the German grandmaster is in clear second place with three rounds to go. | Photo: Crystal Fuller / Saint Louis Chess Club
