Norwegian grandmaster Magnus Carlsen reached a major milestone last week by completing an unbroken 15 years as the world number one in chess, according to The Guardian.
The 35-year-old maintained his top spot in FIDE's official monthly ratings despite a recent subpar performance in Oslo, where he finished fourth out of six players.

His lead remains substantial, with an advantage of more than 30 rating points over closest American rivals Fabiano Caruana and Hikaru Nakamura.
Historic Reign and Comparisons
Carlsen's continuous reign owes some fortune to his 2018 world title match against Caruana, which was tied 6-6 after all classical games were drawn before Carlsen won on speed tie-breaks.
Caruana had a forced checkmate during the sixth game, but the sequence required 58 moves, making it nearly impossible for a human to visualize.
After surpassing Garry Kasparov's peak of 2851 rating points, Carlsen attempted to reach 2900 on three occasions, coming closest in the first half of 2019.
The debate over the greatest chess player continues, as Kasparov held the world number one spot continuously from 1986 to 2006 and faced exceptionally strong opponents, including five epic title matches against Anatoly Karpov.
High-quality matchups where both players were near their peak remain rare, such as Capablanca vs. Alekhine in 1927 and Botvinnik vs. Smyslov.
All five Kasparov-Karpov matches maintained high quality, while only the Caruana series reached a similar caliber for Carlsen.
