Ju Wenjun

Ju Wenjun (born January 31, 1991, Shanghai, China) Chinese chess player who became the women’s world chess champion in 2018.

Ju learned to play chess at the age of seven, when she chose lessons as something interesting to do after school. She soon started to do well against local players her same age and in national tournaments. She came to prominence when she was in a three-way tie for second place at the 2004 Asian Women’s Chess Championship. Her strong showing at that event led to an invitation to the 2006 Women’s World Chess Championship where she was eliminated in the third round.

Between 2008 and 2017 Ju played in five matches for the world championship but did not earn the title. In 2010 she became the Chinese champion, and she claimed that title again in 2014. That same year she was awarded the title of grandmaster.

Ju won the 2015–16 Women’s Grand Prix, a series of five matches, which gave her the chance to face Tan Zhongyi of China for the world championship in May 2018. Ju won three games, drew five, and lost two to win the title. Her match against Tan had been delayed from 2017, so Ju had to defend her title just a few months later, in November at the 2018 championship match. Ju’s second championship match was a knockout tournament with 64 players. Ju advanced to the final, where she played Kateryna Lagno of Russia. Ju and Lagno were tied after four games, and they then played four rapid tiebreakers in which Ju drew two games and won two to retain her title. She became the second woman to retain her title at a knockout match; Xie Jun was the first, in 2000.

In 2018 former Russian deputy prime minister Arkady Dvorkovich was elected president of the Fédération Internationale des Échecs (FIDE), chess’s international governing body. Dvorkovich changed the process of the women’s championship to be more like that of the men; that is, there would be no 64-player knockout tournament but rather a Candidates Tournament in which eight of the top women players would compete to face Ju. In January 2020 Ju faced the 2019 Candidates Tournament winner, Aleksandra Goryachkina of Russia. After 12 games, Ju and Goryachkina were tied, and Ju defeated her by winning one and drawing three of the four rapid tiebreaker games.

Ju faced Lei Tingjie of China to defend her title in July 2023 in a 12-game match. In the first 11 games, Ju and Lei each won one game and tied the rest. In the last game, Ju skillfully played an endgame with both knights, a rook, and a passed pawn against Lei’s two rooks to win and retain her title. Earlier in 2023, Ding Liren had won the men’s championship so both the men’s and women’s chess champions were from China.
