A screen is a device used in some tournaments in duplicate bridge that visually separates partners at the table from each other, in order to reduce the exchange of unauthorized information and prevent some forms of cheating. It is a panel made of plywood, spanned canvas or similar material, which is placed vertically, diagonally across the playing table, with a small door in the center and a slit beneath it. The door is closed during the bidding stage, and the players place their calls using bidding cards on a movable tray, which slides under the door. After the opening lead, the door is opened, but its size allows the players only to see the hands and cards played from the opposite side of the screen, not their partner's face.

The Blue Team represented Italy in international contract bridge tournaments, winning sixteen world titles from 1957 through 1975. From 1964 to 1969 and during a 1972 comeback, the team comprised three regular pairs: Walter Avarelli–Giorgio Belladonna, Pietro Forquet–Benito Garozzo, and Massimo D'Alelio–Camillo Pabis Ticci. Eugenio Chiaradia and Guglielmo Siniscalco played in early years; Dano De Falco, Arturo Franco, and Vito Pittalà in late years. The spiritual father, long-time coach, and non-playing captain through 1966 was Carl'Alberto Perroux.
