Five players are sharing the lead with perfect scores after three rounds at the Qatar Masters in Doha. Arjun Erigaisi, Javokhir Sindarov (pictured), Naryanan S L, Rinat Jumabayev and Robby Kevlishvili are the co-leaders after Friday’s round. Due to the controversy surrounding Magnus Carlsen’s defeat and ensuing social media post on Thursday, the organizers put forth new anti-cheating regulations. Carlsen bounced back from the shocking loss by beating Al Muthaiah with the white pieces. | Photo: Aditya Sur Roy
