Tournament leader Magnus Carlsen was defeated by Fabiano Caruana from Italy during the fourth round of the Vugar Hashimov Memorial on April 24.
The reigning World Champion from Norway surrendered on the 52nd move and suffered a defeat in this rank for the first time.
Commenting on the victory of the Italian chess player, Carlsen said it was always unpleasant to lose.
"Honestly, I was in a bad mood for the whole day," he said. "But Caruana did everything well. I need to try to find a source of energy somewhere to play well tomorrow and relax on Friday."
Caruana, in turn, associated his victory with correct preparations.
"My opponent made a mistake. I correctly understood the situation and then won. The victory brought me pleasure. Victory over the world champion brings even greater joy. We have played a lot with Magnus Carlsen. To tell you the truth, there were sets in which I lost," the winner said.
The match between Azerbaijan's Teymur Rajabov and U.S. Hikaru Nakamura ended in a draw. The set between Russian Sergei Karjakin and Azerbaijan's Shahriyar Mammadyarov did not yield positive results either.
The Russian chess player said he considered the draw a normal result.
"Despite two defeats, Mammadyarov is a very strong player and dangerous for all," Karjakin said after the game.
