    Double - A double of opponents' Notrump contract based on a long running 
    suit, asking partner to lead their short suit without primary honors.  
    In Mike Lawrence's
        
        Double! New 
        Meanings For An Old Bid, he refers to this as 
    "You-Figure-Out-What-Suit-I-Want Double".  Perhaps you are holding 
    something like:

        |  | (P) | X | AP |  |  In this 
    auction, North is asking partner to lead a Spade in an attempt to promote 
    the suit before opponents establish their perceived long Club suit.  
    South probably has few honors and a short Spade suit; thus a Spade lead will 
    allow North to establish the long running suit. 
    Incidentally, when the opponents have voluntarily bid 3 Notrump and the 
    player not on lead doubles, the double requests partner to make a setting 
    lead based on the following priority:
 
      
        | 1. | The suit bid by the opening 
        leader |  
        | 2. | The suit bid by the doubler |  
        | 3. | Dummy's first bid suit, 
        likely a four card suit as opposed to a long suit (rebid) |  
        | 4. | If none of the above apply, 
        use the Lightner Game Double criteria - asking partner to lead their 
        short suit without primary honors |  Also see books on
