Do you know why Magnus Carlsen started playing chess?
He told Joe Rogan in 2025, sitting in a relaxed conversation, exactly how it happened: "I really, really wanted to beat my sister as well at generally everything. From there on, it really just became my thing."
His older sister Ellen was a year and a half older than him. She was playing chess with their dad.
Magnus started sitting in on their sessions and then the competitive part of his brain switched on and never switched off.
I think we are genuinely lucky to be alive in a generation where we can watch Magnus Carlsen play chess. We are watching history happen in real time, and sometimes that fact gets buried under the weekly results and the tournament standings.
So today, I want to gush over him a little bit.
Reign As World Champion
Carlsen became World Chess Champion in 2013 by defeating Viswanathan Anand when he was 22 years old. He had already been world number one since 2011, the youngest person in history to hold that position.
Carlsen held the World Chess Championship title from 2013 to 2023, successfully defending it five times against Viswanathan Anand (2014), Sergey Karjakin (2016), Fabiano Caruana (2018), Ian Nepomniachtchi (2021), and Nepomniachtchi again (2023).
He then voluntarily vacated the title.
And then he walked away undefeated because, as he explained publicly, the format no longer excited him enough to justify the preparation.
Carlsen's peak rating of 2882 is the highest in chess history. He also holds the record for the longest unbeaten streak at the elite level in classical chess at 125 games.
Honestly, the 125-game unbeaten streak is the number that stops me every time I think about it.
The Early Years
Here's something I found that doesn't get mentioned enough. Before chess fully consumed him, Carlsen displayed remarkable intelligence as a child, mastering complex Lego builds and memorizing vast amounts of geographical data before discovering chess. By age five, he could name every country's capital, flag, and population size.
His father, Henrik, described the early years with the kind of honest simplicity that makes a parent worth listening to.
He said Magnus learned the moves at five but didn't fall in love immediately. He just sat near the board and watched for a few years. Then something shifted. "From there on, it really just became my thing."
Magnus once said something in the podcast that I think about a lot. He described his peak form as "a state of flow where I know how much risk to take."
The best chess player in the history of the game is describing what he does at his absolute best, and he sounds like a musician describing a perfect performance.
Magnus Carlsen is the only player to defend a world championship title in speed chess, and the only one to defend a double in rapid and blitz. He won classical, rapid, and blitz world titles simultaneously three times over.
Would you have guessed that all of this started with a boy watching his sister across a board, deciding he needed to be better than her at everything?
He got there… and then he kept going until there was nobody left to chase.
I think that's the most human chess story I have ever heard.
