• A variety of the game of bridge in which the players, beginning with the dealer, bid for the privilege of naming the trump and playing with the dummy for that deal, there being heavy penalties for a player's failure to make good his bid. The score value of each trick more than six taken by the successful bidder is as follows: when the trump is spades, 2; clubs, 6; diamonds, 7; hearts, 8; royal spades (lilies), 9; and when the deal is played with no trump, 10.
