Kateryna Lagno of Russia and Norway's Magnus Carlsen defended their titles in the women's and men's blitz competition on Monday.

Humpy started the second day of the blitz competition by winning the first two games. She then shared the lead with Lagno after round 13 with two draws.
After round 13, Humpy and Lagno had 10 points each but the Indian then drew against Russia's Alisa Galliamova in the 14th round to drop to the second position, half-a-point behind Lagno, who had claimed another crucial win.
