Giorgio Belladonna (7 June 1923 – 12 May 1995) was an Italian bridge player, one of the greatest of all time. He won 16 world championship titles with the Blue Team, playing with Walter Avarelli from 1956 to 1969 and later with Benito Garozzo. A leading theoretician, he was the principal inventor of the Roman Club bidding system, from 1956, and with Benito Garozzo after 1969 created Super Precision, a complex strong club based method. He was known as much for his mercurial temperament as for the brilliance of his card play; see, for example, Belladonna coup.
