Armando Acevedo-Millan, born July 4, 1937, is a FIDE master and former champion of Mexico. In 2001, when Nigel Short thought he was playing Bobby Fischer on the Internet, he asked his opponent when he played Acevedo. The response was immediate. “Siegen 1970.” Fischer had played Acevedo in the Siegen Chess Olympiad in 1970. Acevedo played in the 1966 and 1970 chess Olympiads for Mexico. He was the first Mexican FIDE master.
