Polish Grandmaster ends world champion’s 125 game undefeated streak

Jan-Krzysztof Duda defeated world champion, Magnus Carlsen, in the fifth round of the Altibox Norway Chess tournament in Stavanger, which included the world's leading players. The Pole put an end to the 125 game undefeated streak in classic games.

At the halfway point of the event, the leader of the competition is Levon Aronian from Armenia with 11 points. The Pole was promoted to fifth place with 4 points.

The 22-year-old Polish number one's win over the leader of the FIDE ranking and the World Champion in the tournament is the biggest upset of the Norwegian super-tournament. It was the first victory of the Grandmaster from Wieliczka in this event.

Jan-Krzysztof Duda took the game after only 20 moves when he gained a material advantage. The World Champion tried to defend himself from the losing position, but surrendered after 63 moves. According to commentators he could have done so much earlier.

Duda’s victory saw the 29-year-old Norwegian World Champion series of 125 classic games grind to a halt. His previous loss was on July 31, 2018, to Shiriyar Mamedjarov from Azerbaijan during the tournament in Biel, Switzerland.

This was Duda’s second victory over Carlsen this year, and in the last four duels, he clearly holds an advantage with two wins and two draws. The Pole beat him in fast chess games in May in the Lindores Ammey Rapid Challenge online tournament, included in the Magnus Carlsen Invitational cycle.

Altibox Norway Chess in Stavanger is the first chess super tournament after the competition was suspended in March due to the coronavirus pandemic. It will last until October 16, and the prize pool is NOK 1.81 million (PLN 746,000). The winner is to take home NOK 700,000 (PLN 288,000).
