Vaishali Rameshbabu — “Vaishali” to the chess world, and often written “R Vaishali” in the South Indian style, where Rameshbabu is her father’s name — is the Indian grandmaster who turned a fighting, attacking game into one of the feel-good stories of modern chess. She earned the grandmaster title in 2024, won the FIDE Women’s Grand Swiss twice (2023 and 2025), and in 2026 won the Women’s Candidates Tournament to become a challenger for the Women’s World Championship. Oh, and she’s the elder sister of Praggnanandhaa — together they’re the first brother-and-sister pair in history to both become grandmasters.

Who is Vaishali Rameshbabu?
Born in Chennai in 2001, Vaishali came to chess young — and, as the family story goes, her parents first put her in front of a board partly to cut down her TV time. She trained at the Chess Gurukul academy under respected coach GM R.B. Ramesh (the same coach who later guided her brother), and her progress through the women’s titles came steadily: Woman International Master (WIM) in 2016 and Woman Grandmaster (WGM) in 2018.
The next leaps were bigger. She earned the International Master (IM) title in 2021, and then, in December 2023, crossed the crucial 2500 rating threshold at the IV El Llobregat Open in Spain — completing the requirements for the full Grandmaster title. That made her India’s 84th grandmaster and only the third Indian woman ever to hold the title, after Koneru Humpy and Harika Dronavalli. She’s also the first female GM from her home state of Tamil Nadu.
What is Vaishali’s playing style?
Vaishali is, at heart, an aggressive, attacking player. Coaches and commentators have long pointed to her sharp tactical eye and her comfort in messy, double-edged positions — she’d rather create winning chances than steer for a safe draw. That fighting instinct is exactly why her run to the top has been so watchable.
What’s interesting is how her game has matured. Alongside the tactics, her coach has highlighted flashes of “pure positional class” — including a fine win over elite opposition — suggesting a player still adding new gears. We break the whole package down in Vaishali’s playing style.
What openings does Vaishali play?
As Black against 1.e4, Vaishali’s calling card is the Sicilian Defense — chess’s fightingest reply, and a natural fit for an attacker who wants imbalance and winning chances from move one. As White she plays open, attacking 1.e4 chess. She likes positions where activity and initiative matter more than a memorized draw.
