Walter Avarelli (3 June 1912 – 1987)[1] was an Italian bridge player, a member of the famous Blue Team, with whom he won nine Bermuda Bowls and three World Team Olympiads from 1956 to 1972.
Avarelli was born in Rome and became a judge there.[1] He first took up rudimentary bridge during World War II when more than thirty years old.[2] Along with interests in tennis, riding and motor racing, he was especially noted for "his addiction to gastronomy".[2]
Avarelli was the longtime partner of Giorgio Belladonna using the Roman Club bidding system. They improved the system together and presented it in a book that was published in at least two Italian editions, 1958 and 1969.
