What is the best bidding system which can be used for teaching beginners (who never played bridge before)?
I suspect that showing any complicated system, or asking to learn some long manual would burn all "initial interest". I think it is better to start with real game, and after playing some time (if interest would not be extinguished), having real game experience, beginners would feel natural need by themselfs to improve bidding system.
I can develop some very simple system, but I am curious if there is any standard simple system for learning?
EDIT: After several answers I have to put additional emphasize on what I am trying to achieve. This question is not about mastering Bridge skill from very novice to beginner, but it is about introduction for players who never played bridge (though played some simpler trick-taking games).
I cannot imagine how I supposed to teach beginners rules, game mechanics + material of "first 10 chapters in Commonsense Bidding" or Stayman and Blackwood within 20 minutes just to have first time game. That would take hours without any gaming, and it would become boring and would kill any "initial interest".
Just imagine: "- Guys, let's play Bridge, it is fun and interesting game. But before playing you have to sit down and listen two hours lecture."
What I need is very simple (extremly simple) bidding system, where everything is natural, without any artifical bids. Again, I can develop some very simple system, but I am curious if there is any such standard simple system for learning game play first time?
