Grandmasters Nodirbek Abdusattorov of Uzbekistan and Azerbaijan's Shakhriyar Mamedyarov suffered shock defeats which eliminated them from the International Chess Federation (FIDE) World Cup in Baku.

The 2021 World Rapid Chess Championship winner Abdusattorov drew his first match with 2,585-rated Vahap Sanal at the Baku Marriott Hotel Boulevard before crumbling in the second as white which sealed his fate in the open tournament.

The 2,725-rated Abdusattorov over-pressed despite being in an even position in the second match.

This resulted in him having to sacrifice a number of key pieces before finding himself in a losing position.

Mamedyarov crashed out in similar fashion, this time to Singapore's Tin Jingyao.

The home favourite also made errors in an even position and then was unable to recover. 

His elimination is a huge loss for the hosts as he was one of the country's best hopes to lift the title.

The world’s highest-rated player, Magnus Carlsen scored his second victory.

Despite the Norwegian not being at his best, Georgia's Levan Pantsulaia squandered a major chance before Carlsen finished him off.

Other top seeds that moved into round three were Fabiano Caruana of the United States, his compatriot Leinier Domínguez, and Azeri Teimour Radjabov.

In the women's tournament, former world champion and 2021 World Cup winner Alexandra Kosteniuk lost to China's Yan Tianqi, who has 250 fewer ranking points.

Kosteniuk, now competing for Switzerland having switched nationalities from Russia, opened with a Marshall Attack but it was well countered and she found herself in a weak position in the middlegame.

The favourite then misplayed an inferior ending and was eventually forced to resign.

It is not game over yet for Kosteniuk though as, with one win each, they will play a tiebreak fixture tomorrow to decide who advances to the next round.
