    Unfavorable Vulnerability - A Vulnerable condition may occur on one, 
    both, or neither side of the table, depending on the hand in a match.  
    In Rubber Bridge, the state where the other side has won a singular game.  
    In both Duplicate and Rubber Bridge, the condition where a game or slam bid and made by the 
    oppositions would receive a higher score, but would incur additional 
    penalties for a failed contract. Unfavorable Vulnerability is also known as 
    Red or "Red versus White" (although this board uses the color black instead 
    of white).  See
