Moore was an enthusiastic amateur cricketer, playing for the Selsey Cricket Club well into his seventies. He played for the Lord's Taverners, a cricketing charity team, as a bowler with an unorthodox action. Though an accomplished leg spin bowler, he was a number 11 batsman and a poor fielder. The jacket notes to his book "Suns, Myths and Men" (1968) said his hobbies included "chess, which he plays with a peculiar leg-spin, and cricket." He played golf, and won a Pro-Am competition in Southampton in 1975.
