    Cappelletti, Hamilton, Pottage - A defensive 
bidding system against opponents' 1 Notrump opening bid (often called Hamilton 
in the Western United States, or Pottage in England): 
    
    Standard Cappelletti: 
    
      
        | Bid | 
        
         Meaning  | 
       
      
        | Double | 
        
         Penalty oriented - showing 
        values equal to 1 Notrump opener.  
         Note - to some, this means 1 Notrump opener's range (weak if opener's range is weak); 
        other partner agreements use doubler's (overcaller) 1 
        Notrump opening range (as always 15-17 points). 
        Many play advancer's suit responses are "systems on" (transfers)  |
