Chess legend Susan Polgar hailed Gukesh's mentor, Viswanathan Anand, for his contribution to chess after the 18-year-old became the youngest world champion in the sport's history.

“To my friend @vishy64theking, your vision and passion for chess have come a full circle! Your place in chess history, on and off the chess board, is now inscribed in stone! Congratulations,” she wrote on X.

Indian teenager Gukesh D became the youngest chess world champion on Thursday after beating the defending champion, Ding Liren of China, in the final match of their series in Singapore.

Gukesh, 18, secured 7.5 points against 6.5 of his Chinese rivals in the contest, surpassing the achievement of Russia's Garry Kasparov who won the title at the age of 22. 

The Indian teen prodigy has long been considered a rising star in the chess world after he became a chess grandmaster at 12. He had entered the match as the youngest-ever challenger to the world crown after winning the Candidates tournament earlier this year.

Polgar also said Gukesh will inspire millions of kids around the globe and will be the best Chess ambassador. “The moment so many have dreamed about but only 18 on the entire planet in the history of chess have experienced it! And this 18-year-old, the youngest ever, the undisputed champion of the world, just had his name engraved to this illustrious list,” added Polgar.
