KD Joshi system was one of the 'Modular' approach systems as I would term it. At different places, similar other systems were played/written about as Tim Burke gave me to understand. You show your strength in High Card Points first time, and suits and support on subsequent rounds. It is the simplest system one could think of and I would recommend every bridge player to learn it as a first system. It is unfortunate that it is classified as an artificial system these days but that is the way it is. I had a shock of my life when I was told that it was 'illegal' in England (EBU official correspondence). An elderly couple has been harassed for last two years simply because they play this system or a certain tweak of it. Ever since I came to know of the story, I have been feeling sick about Bridge laws and the current system policies.
