Judit Polgár's IQ is usually cited at around 170, from childhood testing within her father's educational programme. Credible as test results, but self-documented — not published in the psychometric literature like Terence Tao's.
A thesis, written before the daughters were born
Her father László, an educational psychologist, argued that expert performance comes from focused early training rather than innate talent. With his wife Klára, a teacher, he decided to test it by raising their daughters as chess players.
They won special permission to home-school — rare in 1970s Hungary — and made chess the core of the curriculum. László documented the plan in letters and later in Bring Up Genius! (1989).
Judit learned at five, was beating professional masters at nine, and at twelve was the highest-rated woman in the world.
Education: the home curriculum
What the Polgár home school actually taught, beyond the thesis. Each subject was a lesson plan — chess was simply the largest.
Openings, tactics and endgames from László's card index of hundreds of thousands of positions, plus endless blitz against her sisters Susan and Sofia.
Home-schooled under special permission; the girls sat annual exams at a Budapest school to keep their records official.
Esperanto first, then English, Russian and German — useful for playing abroad.
Taught as part of the core curriculum alongside chess.
Table tennis, swimming and running to build stamina for long games.
International tournaments from childhood served as geography and language lessons.
Beating Fischer's record by 34 days
She became a grandmaster younger than anyone before her, of either sex — breaking a record Bobby Fischer had held since 1958, and refuting the claim that a woman could not reach that level.
“I always wanted to be the best chess player in the world, not the best woman chess player.”
She declined the women's championship cycle entirely and played open events against the strongest men — a deliberate competitive and political choice no other top woman of her generation made. She also won the Hungarian national championship outright against male fields.
Eleven world champions beaten
Across classical, rapid and blitz. The most-cited win came in 2002 against Garry Kasparov — then the world's top-rated player — at Russia vs the Rest of the World.
Titles, books and projects
Beyond the record, the open events and the champions she beat.
With her sisters, Hungary ended the Soviet team's long winning run.
A second team gold before she left women's events for good.
Won a ten-game exhibition match 5½–4½ against the former world champion in Budapest, aged 16.
Founded an annual Budapest festival promoting chess in education and culture.
Illustrated workbooks teaching young children chess alongside maths and language.
Volume one of her annotated games, covering her childhood and teens.
Volume two: her climb into the world's top ten.
Volume three: her games against the world's best.
She retired in 2014 on her own timing, the same year Hungary won Olympiad team gold, to focus on family and education. Her foundation's Chess Palace programme teaches chess as cognitive training in primary schools, in Hungary and abroad.
She commentates at World Championships, wrote a three-volume games collection, received Hungary's Order of Saint Stephen, and lives in Budapest with her husband Gusztáv Font and their two children.

Family-administered childhood testing, documented by the programme itself rather than by an independent third party. Her FIDE record is the stronger evidence of what the programme produced.
