Defending champion Anish Giri remains the sole leader of the Tata Steel Masters after six rounds. The Dutchman could have increased his lead, though, as he failed to convert an advantageous position against Parham Maghsoodloo on Friday. Standing a half point back is Alireza Firouzja, who bounced back from his round-5 loss by beating Wei Yi with white. In the Challegers, Erwin l’Ami escaped with a draw in his game against second-placed Anton Korobov to keep the sole lead. | Photo: Tata Steel Chess Tournament / Lennart Ootes
