PLAFOND

(French: Ceiling), French card game popular in Europe in the 1920s, a predecessor of Contract Bridge. Trick values and scoring were as in Auction Bridge except that, as in Contract Bridge, only tricks bid and made counted toward game; overtricks scored 50 points each in the honour score, which did not count toward game score, and slams, bid or unbid, scored 100 points for small and 200 points for grand. In 192526 Harold S. Vanderbilt, expert Auction Bridge player, revised the scoring table and added the factor of vulnerability. His changes were incorporated into the game of Contract Bridge, which replaced Plafond in popularity in the 1930s.
