Shambavi Hariharan, aged 15, has won the under-18 girls’ title at the 2026 Delancey UK Chess Challenge Terafinal.
The Oxford High School pupil, who is from Kidlington, competed at Blenheim Palace across October 17 and 18.
The two-day national finale concluded Britain’s largest junior chess competition, which attracts approximately 20,000 children annually.
Following regional qualifying rounds, 60 players advanced to the final, where they contested an 11-round format in which each finalist met every other competitor across five age categories.
Hariharan accumulated seven points from 11 encounters in the mixed under-18 division.
The three leading finishers overall each gained one point more than the Oxford student, whose total nevertheless secured the girls’ championship in her category.
The title adds to Hariharan’s existing achievements in the game.
She had already become a Woman FIDE Master after sharing first place in the English Women’s Championship.
Hariharan began playing chess roughly five years ago.
Her mother introduced her to the basic elements, while membership of a chess club at her previous school provided the initial spark for her continued involvement in the sport.
She also values the mental demands of chess and believes there is always more to learn.
Hariharan said the game has developed transferable abilities that she can apply away from the board.
Her interests outside chess include Formula One, reading and music.
Sarah Longson, chief executive of the Delancey UK Chess Challenge, praised Hariharan’s displays during the weekend.
She regarded the seven-point return from such a competitive under-18 field as a tremendous accomplishment.
Longson also noted that Hariharan had attained the Woman FIDE Master title and performed successfully in the English Women’s Championship before reaching the age of 15.
According to Longson, Hariharan’s victory provides an example for other young chess players.
The UK Chess Challenge aims to increase participation among girls while encouraging them to remain involved in the game as they grow older.
Longson expressed hope that Hariharan’s success would prompt other girls to pursue the same path.
The Delancey UK Chess Challenge was launched in 1996 and has since provided opportunities for more than one million children.
The 2026 Terafinal was the final event staged under Delancey’s sponsorship, ending a lengthy period of backing for junior chess throughout the UK.
