Four players are necessary for a game of bridge, but after the bidding only three actually play. The players sitting opposite each other are partners. After the bidding, only one of the partners who won the contract gets to play. The other is the 'dummy' and lays his cards face up on the table. The 'declarer' plays his own hand and the dummy's hand, too.

The Roman Key Card Blackwood bridge convention is a bidding system used in the card game bridge to determine the number of key cards (aces and the king of trumps) held by the partnership. It is used to assess the strength of the partnership's hands and help them decide on the final contract to bid. This convention is commonly used in competitive bridge games to exchange information about key cards and make more informed bidding decisions.
