Norway's Magnus Carlsen lost two of his world titles at the International Chess Federation's World Rapid and Blitz Championship in Warsaw, with Uzbekistan's Nodirbek Abdusattorov clinching the men's crown in the former and Maxime Vachier-Lagrave of France winning in the latter discipline.

Carlsen entered the Championships at the Narodowy Stadium as world champion in the classic, rapid and blitz disciplines.

He led the rapid standings going into the final day of competition, but lost a crucial match against Abdusattorov after a wrong plan on move 81.

After 13 rounds, four players were tied on 9.5 points, with the 17-year-old Abdusattorov winning a playoff against Ian Nepomniachtchi of the Chess Federation of Russia (CFR), with Carlsen in third.

In the blitz tournament, Vachier-Lagrave was one of three players to finish on 15 points after 21 rounds.

He triumphed in his play-off against Polish home favourite Jan-Krzysztof Duda, while fellow Frenchman Alireza Firouzja placed third with an inferior tiebreak score.

In the Women's World Blitz Championships, Bibisara Assaubayeva of Kazakhstan notched an impressive victory with a round to spare.

The 17-year-old scored 14 points as she dominated the tournament, with the nearest challenger of the CFR Alexandra Kosteniuk collecting 12.5.

However, in the rapid discipline, Assaubayeva had to settle for second with 8.5 points as Kosteniuk was unbeaten in 11 rounds on her way to victory, notching nine points.
