Magnus Carlsen breaks down his chess mind, why he walked away from the World Championship, and his fun-first philosophy of life.

Magnus Carlsen — Norwegian chess grandmaster, the world's number-one ranked player and widely considered the greatest of all time. He has held the world No. 1 ranking since 2011 and was reigning World Champion at the time of recording.
Magnus Carlsen joins Lex Fridman for a wide-ranging conversation about what makes him so dominant at chess, from his elite evaluation and intuition to his legendary endgame play. He explains his decision not to defend the World Championship title, arguing the format is too small a sample size and brings out fear of losing rather than joy. The two compare greatness across sports (Messi, Jordan vs LeBron) and chess legends (Fischer, Kasparov, himself), and dig into engines, neural networks, openings, and chess variants like Fischer Random. Carlsen also opens up on diet, alcohol, fasting, exercise, his father's influence, loneliness, poker, and his belief that life is meaningless but still worth enjoying for fun.
