Hi, everyone. This is my first post, so I hope I chose an appropriate board. Background: wife and I just joined a regular duplicate game and need a more formalized bidding system. We're using SA based on the following point zones: 0-5,6-10,11-12,13-15,16-18,19-21,22+. To simplify difficult situations (remember, we're novices as a dup p-ship) we're working on the following idea, that summarizes some common guidelines, but I don't think I've specifically seen it written this way: A good hand is 16 for opener, 11 for responder; so game requires one good hand. Responder needs a good hand for 2-level; after that, no one goes to 3 without good hand by either player (except: as obvious, final correction to best suit.) Double means a good hand after opp open or overcall in first round (natural bids still allowed). We're looking to find if this concept is described and futher developed in a published source. If you know of one, we'd love to hear. Thank you and I hope this is in line with board protocols.
