Tales of courage
Ugandan teenager, Phiona Mutesi, grew up in poverty, unable to read or write. Her father died
when she was very young and she had to find food for herself and her brother. It was that basic
need that decided her fate, because it led her to Robert Katende's chess programme. Katende was
offering a bowl of food to any child who would come to his centre to learn chess. Phiona
wouldn't have gone there if she hadn't been desperate to eat, and her life changed with that one
decision. Her potential at chess was obvious from the start and she enjoyed playing, so began to
practise more and more. She walked four miles a day to attend training, collecting food each
time. She was soon beating the older girls and boys in the programme and has since played for
Uganda in several international tournaments, with trips to Russia, Turkey and the USA. Phiona
has brought hope to her family and is becoming an inspiration worldwide, with the recent
appearance of her biography.
Koni Dole's bravery and fighting spirit are remarkable. Koni comes from Montana in the USA
and is passionate about American football. He regularly represented his high school in
competitions until he suffered a bad break to his leg, which became infected after it was set.
Eventually, Koni's leg had to be removed and doctors told him he would never play football
again. However, instead of letting himself be beaten, he faced up to his disability and used it as
motivation. Immediately after the surgery, he began training again and, with the help of an
artificial leg, went running and lifted weights to improve his fitness. Despite being in great pain
at times, he continued the training programme and returned to the football field a year after his
terrible accident. Koni has been given a football scholarship by Montana State University and
fully intends to achieve further sporting success.
