All four groups have sole leaders after six rounds of the Total Chess Pilot in Budapest. Alireza Firouzja (Group A), Fabiano Caruana (Group B), Haik Martirosyan (Group C) and Maxime Vachier-Lagrave (Group D) are currently in first place, with Caruana continuing to lead the overall scoring table. Friday's most notable result was Martirosyan's victory over Magnus Carlsen, which had major implications for the live classical ratings.
Caruana remains the tournament's top scorer after collecting a win and a draw against Vincent Keymer on Friday. The five-time US champion now has 14 points from six games, having recorded four wins and two draws.
Vachier-Lagrave, meanwhile, has scored a win and a draw in each of his three mini-matches, including Friday's encounter against former co-leader Hans Niemann. The Frenchman leads Group D with 12 points, the second-highest tally in the event.
In Group A, Firouzja suffered his first defeat of the tournament at the hands of Andrew Hong, who outplayed the Frenchman with the white pieces in a double-edged Sicilian. Firouzja bounced back with a win and remains the sole leader with 11 points. Standing in sole second place, 2 points back, is Jan-Krzysztof Duda.

The biggest surprise came in Group C, where Haik Martirosyan defeated Magnus Carlsen in their first-ever classical encounter. The Armenian had exchanged wins with Shakhriyar Mamedyarov and Anish Giri in his first two mini-matches, and his victory over Carlsen helped him reach 10 points. Martirosyan confessed afterwards:
It's like a dream for me. I just dreamed to play against him in classical chess, but to win it, it's really special.
In their second encounter, Carlsen opted for a risky line featuring an early g2-g4. The Norwegian could have found himself in real trouble again had he continued playing adventurously, but the game eventually ended in a draw by repetition. Carlsen has thus collected five draws and one loss so far in the group stage.
Since the fast classical games count towards the official classical ratings, Carlsen's results have affected the top of the live rankings. He has lost 15.8 rating points, dropping to 2807.2, below his lowest official rating of the past decade (2822 in August 2017). Caruana, on the other hand, has gained 17 points and returned to the 2800 mark, leaving him just 7.2 points behind Carlsen. The Norwegian has held the official world number one ranking continuously since July 2011, a streak spanning more than 15 years.
