The winner would be the new women's world chess champion. The final was won by Tan Zhongyi over Anna Muzychuk in the rapid tie-breaks.

Other top players, the 2015 Women's World Champion, Mariya Muzychuk, and US Women's Champion Nazi Paikidze did not participate either because it is mandatory for women in Iran to wear a hijab in public. World number 4 Humpy Koneru and 7-time US Women's Champion Irina Krush did not participate as well...
