Chingaiz Khan was an unknown quantity when he arrived for a junior weightlifting tournament in South Waziristan nine years ago.
Chaotic and intensely religious, the Pakistani region is known by locals as "the most dangerous place in the world."
The 12-year-old Chingaiz, with his short, jet-black hair and smooth, unblemished skin, looked younger than the other boys. But, despite it being his first ever tournament, he was still stronger than everyone else.
For his father Shams-Ul Wazir, a local college lecturer, the decision to register his son for the tournament paid off handsomely.
Chingaiz was crowned the junior boys' weightlifting champion, the first step on a journey that would take him into the world of professional sport.
Except Chingaiz wasn't really his name.
Chingaiz was actually called Maria Toor Pakay.
Chingaiz was a girl.
"I suggested the name of Chingaiz Khan for her since she had always been like a boy," explained Al Wazir in an interview with HBO. "She liked the name very much."
Girls and boys
This isn't a story of deception, but rather a tale of necessity.
Maria Toor Pakay is Pakistan's number one squash player, ranked 49th in the world. She also comes from an ultra conservative region in Pakistan that is home to the Taliban.
Female participation in any form of public life is strongly discouraged, by both words and deeds. Education, working, sports; anything involving women leaving the house unaccompanied by a male relative was seen as the work of the devil.
But Pakay had talent. Her weightlifting triumph gave her access to a world of sporting options that would otherwise have been out of bounds to her as a female, and she discovered the discipline where she would make her name.
Squash is one of Pakistan's most popular games and Pakay excelled at it. By the age of 21 she had gone pro and broken into the world top 50, an incredible rise up the world rankings. She is one of only three Pakistani women in the top 200; by contrast the nation has 15 men in the same strata.
Yet her success has come at a price. Pakay and her father have been threatened with retribution by the local Taliban for insulting their culture and their religion.
"My area, my tribal regions are called the hub of terrorism and extremism," said Pakay.
"It's the home to the Taliban, and it's called the most dangerous place in the world. But I have a big vision for my country, and for my people it will be stopped. I always thought that maybe I'm the chosen one."
Pakay realized at a young age that she was different to other people she saw in her community.
"When I was four and a half, I told my parents that I want clothes like my brother," she said.
"I want to play with boys, there's more freedom, I felt. And I am not like girls who play with dolls. I want the toy guns and things like that."
Such behavior was anathema to the deeply conservative community she was born into. But her father agreed. Rather than forcing his daughter to conform, he thought about how best to realize his daughter's talent. It was he who came up with the plan to cut his daughter's hair and enter into competitions with the boys.
"They (religious elders) sent me to a mental asylum 'cause they thought that I had deviated from the culture, and that I was crazy supporting women's rights," he recalled.
"They said I was spoiling the whole environment and that all women would want the same rights."
