R Praggnanandhaa also excelled, defeating Alireza Firouzja in a tie-break after a classical draw, earning him 1.5 points as well.

This result places Firouzja at the top of the standings with three points, while Gukesh and Praggnanandhaa are tied for second. In the women's section, Bibisara Assaubayeva achieved an impressive win over Indian No. 1 Humpy Koneru, leading the women's standings.
