Mangus carlsen
A chess prodigy, Carlsen finished first in the C group of the Corus chess tournament shortly after he turned 13, and earned the title of grandmaster a few months later. At age 15, he won the Norwegian Chess Championship, and at 17, finished joint first in the top group of Corus. He surpassed a rating of 2800 at age 18 years and 336 days, the youngest at the time to do so. At 19, he reached #1 in the FIDE world rankings, the youngest person ever to do so.
Carlsen became World Chess Champion in 2013 by defeating Viswanathan Anand. The following year, he retained his title against Anand, and won both the 2014 World Rapid Championship and World Blitz Championship, becoming the first player to hold all three titles simultaneously, which he repeated in 2019. He defended his classical world title against Sergey Karjakin in 2016, against Fabiano Caruana in 2018, and against Ian Nepomniachtchi in 2021.
