Svyatoslav Bazakutsa took sole possession of the lead at the British Chess Championship after defeating nine-time champion Michael Adams in round four. The 18-year-old Ukrainian now has a perfect 4/4, half a point ahead of a five-player chasing group. Among them is 11-year-old Bodhana Sivanandan, who continued her strong start by beating fifth seed Ameet Ghasi with the black pieces. | Photo: Yury Krylov
