Seventeen-year-old Phiona Mutesi began playing chess for the free meal offered by a church program in the Katwe slum of Uganda. “That’s when I got to practice and I got better. Then I got an interest in chess,” she says. Mutesi won the church tournament five times in a row, as well as the 2009 International Children's Chess Tournament in South Sudan. She recently spoke at the the Women in the World Summit in New York attended by Hillary Clinton and Oprah Winfrey.
