Magnus Carlsen is a Norwegian chess grandmaster who is widely regarded as the greatest chess player today. He became World Chess Champion in 2013 and has remained dominant across multiple formats.
However, Carlsen has also been involved in several controversies within the chess world. He declined to defend his World Chess Championship title in 2023 and has faced criticism for professionalism issues, including lateness, dress code violations, and public disputes involving allegations of cheating. More recently, he has clashed with FIDE after criticizing existing regulations and promoting alternative formats such as freestyle chess.
