Barbu is a skilful card game for four players. It uses a standard 52-card pack as for bridge or poker, ranking as usual from highest to lowest Ace K Q J 10 9 8 7 6 5 4 3 2 in each of the four suits. In the course of a session, each player will play each of the seven contracts once, so that there are 28 hands played in all. The initial declarer is chosen at random. For the first seven hands, this player will be declarer. The cards will be dealt by the player on the declarer's right, and cut by the player opposite to declarer. After this declarer has done her seven contracts, the player on the original declarer's left will be declarer for seven contracts, and so on, until everyone has done her seven contracts. In each of these contracts, each player is playing for herself. Declarer chooses the contract, but there is no reason for the other players to co-operate against her. The rules about doubling, however, are asymmetrical with respect to declarer Research Barbu
