Stavanger (Norway), Indian Grandmaster R Praggnanandhaa claimed his first classical game win over world number one Magnus Carlsen and took the solo lead in the Norway chess tournament here.

The 18-year-old Indian, who has defeated Carlsen several times in rapid/exhibition play, moved into the lead with 5.5 points after three rounds.

Praggnanandhaa was playing with white and his win moved home favorite Carlsen to fifth place in the points table.

Classical chess, also known as slow chess, allows players a considerable amount of time to make their moves, usually at least an hour.

Carlsen and Praggnanandhaa had played out draws in their last three matches in this format.

Praganandha's sister R Vaishali also topped the women's competition with 5.5 marks.

She drew her match against Anna Muzychuk.

In other sports, world number two Fabiano Caruana of America defeated current world champion Ding Liren of China. After the defeat, Liren dropped to the bottom of the six-player field.

American Hikaru Nakamura won his Armageddon game against Alireza Turquoise o France to earn an extra half point and move into third place in the standings.

Nakamura will face Praggnanandhaa in the fourth round.
