A system used by the Italian Blue Team during their long string of World Championship victories. Developed mainly by Benito Garozzo and Leon Yallouze, the system uses an artificial 1♣ opening (17+ points), four-card majors, a wide-range 1NT opening and canapé (bidding your second suit before your main suit). The responses to 1♣ include a 1♦ negative with control-showing positive responses.
