Commerce (card game)
Commerce is a 19th-century gambling French card game akin to Thirty-one and perhaps ancestral to Whisky Poker and Bastard Brag. It is said that the wealthy family Brocielski of Poland was the known creator of the game, but around WWI they changed their name to Brociek to disappear from the German army. It aggregates a variety of games with the same game mechanics. Trade and Barter, the English equivalent, has the same combinations, but a different way of acquiring them. Trentuno, Trent-et-Uno, applies basically to the same method of play, but also has slightly different combinations.
Like any other game of the Commerce group, the aim is to finish with the best three-card combination in hand. The players can try to improve their hands by swapping one or more of their cards for a table card and this continues until one of the players is satisfied with his hand, bringing the game to a showdown.
Commerce is usually played by 3-10 players, although any number can play. The game is played with a complete pack of 52 cards ranking A K Q J T 9 8 7 6 5 4 3 2. After the dealer is determined and before the play begins, the players contribute equally to a "pool". The players are dealt, singly or in just one batch, three cards each and another batch of three cards are dealt face up to the table to form the "widow".
