Round two of the Sinquefield Cup in Saint Louis produced two decisive games, as world champion Gukesh Dommaraju bounced back from his opening-day loss with a chaotic win against Nodirbek Abdusattorov, while Alireza Firouzja turned the tables in a 100-move struggle against Jan-Krzysztof Duda. The remaining three games were drawn, leaving Firouzja, Levon Aronian and Praggnanandhaa Rameshbabu sharing the lead on 1½ points. | Photo: Lennart Ootes
