I want a discard system to signal my partner a suit preference which does not involve discarding with high cards, or signalling with alternative options. Hence Attitude, Roman, Revolving Discards, Laventhal, McKenney all require high card discards or high/low signals, or odd/even signals. The system I prefer (and I can’t find where it originated from) is very simple. The card I discard signals that I want the suit above (skipping the missing suit). Therefore, if I want a spade, I discard a heart; if I want a heart I discard a diamond, if I want a club I discard a spade. This is somewhat like revolving discards, but doesn’t involve the option of low or high discards. It seems to me that discarding a high card in a suit that you want to take tricks in is wasteful. And the various options in other systems mean partner has to work out what you want led. So, what is wrong with a very simple system? Where does it fall down?
