Is FIDE planning to start investigation against Ding's last game defeat? According to a Russian news agency, a  controversy has come up surrounding the World Chess Championship which was clinched by D. Gukesh. Russian Chess Federation president Andrey Filatov has alleged that China’s Ding Liren intentionally lost the final match. 

Gukesh defeated reigning World Champion Ding Liren in the 14th classical game to clinch the title, on Thursday. After 13 matches, both players were tied on points. Gukesh’s victory in the final match crowned him the youngest World Chess Champion. However, the win has now come under scrutiny.

Filatov raised concerns, stating, "The final game of the World Championship surprised everyone. The way Ding Liren lost was suspicious. FIDE should investigate this. It’s difficult for a top-class player to lose from the position Ding was in. His loss seems intentional.”

Throughout the championship, Gukesh played an aggressive game style, while Ding remained largely defensive. The same pattern continued in the final game. Under time pressure, Ding struggled in the endgame. After 40 moves, Ding had only a king and one pawn left against Gukesh’s king and two pawns. The game appeared to be heading toward a draw when Ding made a critical mistake.

Ding’s error came on his 55th move, a blunder he realised immediately after making it. Speaking after the match, Ding said, "Under pressure, I made a mistake in one move. Right then, I could see how happy Gukesh was. There was nothing I could do after that.”

Gukesh also admitted he didn’t immediately grasp the enormity of Ding’s mistake. "At first, I didn’t realise Ding had made such a big error. It took me a few seconds to understand, and I capitalized on it," said Gukesh.
