World chess champion Magnus Carlsen has suffered his first defeat in more than two years and a record 125 games, while playing a tournament in his native Norway. The world number one resigned after when he was a bishop down in the endgame against Polish grandmaster Jan-Krzysztof Duda, who is ranked a relatively humble number 15 in the world.

But on Saturday evening, 22-year-old Duda managed to do what no one -- including the world's top 10 players -- had managed to do since July 2018. It was Duda's only win of the tournament in Stavanger so far and, as he told Chess 24 afterwards, "I didn't expect to win this game."
