Hou Yifan: Biography, Achievements & Lasting Legacy

Hou Yifan (Chinese: 侯逸凡; pinyin: Hóu Yìfán ; born 27 February 1994) is a Chinese chess grandmaster, four-time Women's World Chess Champion and professor at Peking University. She is the second-highest-rated female player of all time. A chess prodigy, she was the youngest female player ever to qualify for the title of grandmaster (at the age of 14 years, 6 months, 16 days) and the youngest ever to win the Women's World Chess Championship (at age 16).

At the age of 12, Hou became the youngest player ever to participate in the Women's World Championship (Yekaterinburg 2006) and the Chess Olympiad (Torino 2006). In June 2007, she became the youngest Chinese Women's Champion ever. She achieved the titles of Woman FIDE Master in January 2004, Woman Grandmaster in January 2007, and Grandmaster in August 2008. In 2010, she won the 2010 Women's World Championship in Hatay, Turkey at age 16. She won the next three championships in which the title was decided by a match (in 2011, 2013 and 2016, with a total of ten wins to zero losses and fourteen draws against three different opponents), but was either eliminated early or she declined to participate in the championships in which the title was decided by a knockout tournament (in 2012, 2015 and 2017).

Hou was the third woman ever to be rated among the world's top 100 players (2014–16 and 2017–22), after Maia Chiburdanidze and Judit Polgár. After Polgár's retirement, she was widely regarded as the strongest active female player, maintaining a substantial rating lead over her peers. She has been the No. 1 ranked woman in the world since September 2015, but has been largely inactive since 2018. She was named in the BBC's 100 Women programme in 2017. In 2020, she became the youngest professor at Shenzhen University at the age of 26, and has since moved to Peking University.
