    Rule of 20 - Refers to a secondary hand evaluation methodology when a 
    hand does not have sufficient strength to open bidding using a traditional 
    point count.    A player may open the bidding when the High Card Point sum added to 
    the number of cards held in the two longest suits totals 20 or more.  
     
     Note: the player's honors should be in the long suit/s, not 
    side suits (i.e., no defensive tricks) 
      
        | High Card Points in 2 longest suits | Combined 
        number of cards in 2 longest suits | Sum |  
        | 9 | 11 | 9+11 = 20 |  
        | 10 | 10 | 10+10 = 20 |  
        | 11 | 9 | 11+9 = 20 |  
        | 12 | 8 | 12+8 = 20 |  Also see Rule of 15 |
