La Grand echiquier, or The Grand Chessboard, was a television show that
aired on two of France's networks: Channel Two ORTF and Antenne 2, from
1972 to 1986. The show was created and hosted by Jacques Chancel. One
guest, usually a prestigious person like actor Lino Ventura or a
musician like trumpet player Maurice Andre, would come on the show and
stay for about three hours while Chancel interviewed them. The program
alternated between the interviews of the main guest, outside reporting,
informal discussions, and musical interludes.
