R Vaishali, the reigning World Championship Challenger, clinched the title at the opening event of the WR Women's Chess Tour in Tokyo, Japan on 6 June, hours after her brother Grandmaster Rameshbabu Praggnanandhaa became the first Indian to win the Norway Chess championship. The Chennai siblings scripted a historic double on the same day, marking an extraordinary moment for Indian chess.

How Vaishali Won in Tokyo

The 24-year-old from Chennai dominated the eight-player rapid event, played at a time control of 15 minutes with a 10-second increment per move. In the quarterfinal, she defeated IM Irine Sukandar, winning one game and drawing another for a 1.5-0.5 verdict. She then beat former Women's World Champion Alexandra Kosteniuk of Russia by the same 1.5-0.5 margin in the semifinal.

In the final, Vaishali overcame IM Alua Nurman of Kazakhstan 1.5-0.5 in a two-game match to seal the title. She finished ahead of Kosteniuk, Kateryna Lagno of Russia, and Antoaneta Stefanova of Bulgaria — Women's World Champion from 2004 to 2006. The field also included Anna Sargsyan, Irine Sukandar, Alua Nurman, and Azumi Sakai.

Pragg's Norway Chess Triumph

Praggnanandhaa, 20, scripted what is being described as the greatest comeback in a Super Tournament, winning the Norway Chess title on Friday night after defeating Germany's Vincent Keymer in the 10th and final round of the classical event. Playing with the white pieces, Pragg capitalised on errors by Keymer in the middlegame to win on the 45th move.

He finished the tournament with 18 points from five wins, two losses, and two draws — both of which he converted in Armageddon. The former World No. 4 claimed the top prize of $100,000, finishing a point clear of overnight leader Wesley So of the United States, who drew with Alireza Firouzja in the final round to end on 17 points from two wins and eight draws, winning six of them in Armageddon.

What It Means for Indian Chess

The sibling double on the same day is unprecedented in elite chess. Vaishali had already established herself as a force in women's chess by qualifying as World Championship Challenger; this Tokyo title reinforces her status ahead of that campaign. Pragg's Norway win, meanwhile, confirms his arrival among the world's very best classical players — a feat no Indian had achieved at this event before.

Notably, this comes amid a broader Indian chess surge, with D Gukesh recently becoming World Champion and Indian players dominating global circuits. Having secured the rapid title in Tokyo, Vaishali will next target the blitz event, which begins on Sunday, aiming for a rare rapid-blitz double.
