Truong's father, Tien, was a South Vietnamese official working at the U.S. embassy in Saigon during the
Vietnam War. Truong learned the
rules of chess along with his father at the age of five and played at the National Sports Center (CSS) in
Saigon, a center for chess in the country. From an early age, he won the CSS's annual tournaments, which were informally recognized as the National Championships of South Vietnam. In all, he claims to have won the annual under-21 event four times, starting when he was five years old, and the annual adult event five times, starting when he was eight. Truong has been inactive as a competitive chess player since 1986. ==Chess journalist and photographer==
