Once upon a time a 7-year-old refugee living in a homeless shelter sat down at a chess board. Tanitoluwa Adewumi better known as Tani " enjoyed chess as an escape from the chaos of the homeless shelter, and his skills progressed in stunning fashion. After little more than a year, at age 8, he won the New York State chess championship for his age group. I wrote a couple of columns about Tani at that time, and readers responded by donating more than $250,000 to a GoFundMe campaign for Tani's family, along with a year of free housing. This month, as a fifth grader, Tani ... emerged with a chess rating of 2223, making him a national master. When Tani won the state championship, several private schools offered him places, but the family decided to keep him in the public school that had nurtured him. The Adewumis also used the $250,000 contributed by readers to start a foundation that helps other homeless people and refugees. The larger lesson of Tani's story is simple: Talent is universal, while opportunity is not. In Tani's case, everything came together. His homeless shelter was in a school district that had a chess club, the school waived fees, he had devoted parents who took him to every practice, he won the state tournament (by a hair) and readers responded with extraordinary generosity. My challenge as a columnist is that readers often want to help extraordinary individuals like Tani whom I write about, but we need to support all children " including those who aren't chess prodigies.
