Thought this was a really interesting insight from Sam Shankland about Magnus from an interview he did on chess24
How does Carlsen’s genius manifest itself?
If I knew what made Magnus the genius he is today maybe I would be the World Champion instead of him. He just has this way of looking at the board and he just knows what moves are most critical – not necessarily what moves are best, but what moves are most critical. He’s got this sort of Fischeresque thing when you look at him play. I saw some statistic that of the top 10 players in the world he matches the top choice of the computer the least of all of them… and he matches the top three the most, which essentially means that Magnus might not play the best move any more often than anyone else, but he always plays a good move, and just this lack of serious mistakes, because his natural feel is so great… Again, he’s so much better than me that it’s really hard to comment on it. Even at number 24 in the world there’s so much difference between the two of us. It’s hard for me to truly understand what goes on in his mind, because he’s just so much stronger.
