    Super Gerber (High Gerber)  - In response to partner's Notrump bid, a double-raise 
    (jump) in Clubs above 3 Notrump to 5C asks partner to show Aces held.  
    Some players find regular Gerber reduces ambiguity and allows a non-jump bid 
    of 4C to be used naturally or cuebid to show a Club control.  
    While many non-jump Gerber players find the jump gets the auction 
    unnecessarily too high, Super Gerber bidders feel comfortable making a 5 
    Notrump contract regardless of Aces disclosed. 
     Here are some illustrative auctions: 
      
        | 1C - 3N; 4C
 | 2N - 
    3C; 3D - 4C;
 | 1C - 2D; 3C - 4C;
 | 1C - 1H; 2D - 2S;
 3C - 3S;
 3N - 4C;
 |  Playing Super 
    Gerber, slam Ace asking sequences always begin with a Club jump above 3 
    Notrump.  Using the above examples, Super Gerber Ace asking sequences 
    are: 
      
        | 1C - 3N; 5C
 | 2N - 
    3C; 3D - 5C;
 | 1C - 2D; 3C - 5C;
 | 1C - 1H; 2D - 2S;
 3C - 3S;
 3N - 5C;
