There are 3 articles.  Contract Bridge, Rubber bridge and Duplicate bridge.  It is possible there are more and that I've missed something.  One article is the parent article, it should include some history of how the game developed from Whist and that article would be Contract Bridge.  That there is bidding should be spelled out in the parent article.  That there are only 15 useable words which partners may use to describe their hand and to arrive at a contract should be spelled out, the concept of strain or demonination should be presented and the rules of play.  But I don't believe it would be appropriate to do more than touch on bidding systems.  Rubber bridge is the way Contract Bridge is scored.  Then, Duplicate bidge adds another layer of scoring complexity in addition to the already present and continually used, rubber bridge scoring. In addition, Duplicate Bridge adds another layer of rigidity to what cards partnerships hold.  In this manner the element is skill is boosted while the element of luck (unavoidably present) is made smaller.  The Duplicate bridge article could get into the bidding boxes, the curtain used in large, international tournements and so on.  But I would very much like to see these articles be friendly and readable so that a person who had never played bridge could read them and could find a logical development of complexity and of expertise required.  So that a green player could view both how to begin to learn to play and where the top is too, that people make their living at playing bridge, that there are international tournements of great interest, that some top bridge players are recognized by various public figures and so on.  So that a person can follow the logical development of being a beginning player, right through to becoming a top player.  And the joy of the intellectual compitition combied with the social intercourse of sitting at a table with 3 people.  We could compare that, perhaps, to Chess which is likewise an intellectual compitition but is less social with each board lasting longer and being less casual.  You know what I mean?  As it stands now a new player isn't introduced to the game in a logical sequence.  This article covers too much ground and brings too much stiffness into the game too early.
