        Isolated Threat (Menace)- One card 
        menace, often an opponents' Queen - here West cannot afford to pitch a

        Split Two Card 
        Menace (Threat)  - A two card menace where the cards are in opposite hands - neither East 
        nor West can afford to pitch a Diamond when void in another suit.  
        Further, with these holdings it is unprofitable for either side to break 
        this suit. 
        Double Menace (Threat) - Holding a card threatening both opponents' (same
