After 1908, Maróczy retired from international chess to devote more time to his profession as a clerk. He worked as an auditor and made a good career at the Center of Trade Unions and Social Insurance. When the Communists came briefly to power in 1919 after World War I (Hungarian Soviet Republic) he was a chief auditor at the Education Ministry. After the Communist government was overthrown he couldn't get another job. He made a brief return to chess, with some success. At the turn of the year 1927/8, he demolished the 1924 champion of Hungary, Géza Nagy, in a match by +5−0=3. With him at the head, Hungary won the first Chess Olympiads in London (1927).
