    On March 10, 2019, eight-year-old Tanitoluwa ''Tani'' Adewumi defeated 73 young competitors to win the New York State Scholastic Chess Championship in his age group — kindergarten to third grade — with five wins and one draw. While the achievement is remarkable in itself, what is even more so is that the youngster, who was homeless at the time, began learning the game less than a year ago.

Tani and his family arrived in New York City from Nigeria in 2017, seeking religious protection. A church pastor(牧师)helped find the family of four space in a homeless shelter in Manhattan and, soon after, Tani entered the local elementary school. It was here that the young talent was first introduced to the basics of chess by a part-time teacher. Attracted by the game, the then seven-year-old begged his mother, Oluwatoyin, to allow him to join the school's chess club. The family were concerned that they would be unable to afford the fees and expenses, which add up to thousands of dollars due to travel and chess competition admissions, Oluwatoyin emailed chess instructor Russell Makofsky, who ran the club. To her surprise and delight, Makofsky agreed to waive all costs for young Tani. The rest, as they say, is history. The young boy, who has got seven prizes in less than a year, currently ranks 27 in America in his age group.

Though the chess club certainly helps, Tani's success can be largely owed to the efforts he has put into the game. The chess talent practices the game for several hours a day either on the floor with his board, or online, using his dad’s laptop. Every Saturday, Tani and his mother head to Harlem for a free 3-hour class to help further sharpen his game skills.

Not surprisingly, Tani's incredible story, first reported by The New York Times, has resulted in an outpouring of support from the American public. Shortly after the young boy won the New York State Championship, Makofsky began a GoFundMe campaign for Tani and his family to ''secure a home where he can continue on his journey''.

And the heartwarming story gets even better! Since they now have a home, the family have decided to ''pay it forward'' and donate the over $200,000 collected on GoFundMe to African immigrants in America who are struggling the way the family was.
