With just three rounds to go in the Rs 6,00,000 prize money championship, Padmini took her tally to 6.5 points out of a possible eight and remained a full point ahead of her teammates Soumya Swaminathan and top seed Eesha Karavade.
While Soumya and Eesha have 5.5 points apiece, none of the other competitors are in any position to challenge Padmini's supremacy and barring a debacle the Odisha girl is likely to clinch the title from here.
In other important games of the day, Eesha defeated M Mahalakshmi with white pieces while Soumya proved superior to R Vaishali who played white.
