| Lightner 
    Double - A Double of opponents' high level auction, often a slam bid, to 
    request partner to make an unusual lead.  The Lightner Double was named 
    after Theodore Lightner in 1929.  The following guidelines apply to 
    Lightner Doubles: 
      
        | 1. | Typically anticipates the 
        player making the Lightner Double can generate the setting trick by 
        either ruffing the lead of a long side suit, or allowing partnership to 
        quickly take their winning tricks before the Declarer sets up a long 
        side suit to pitch losers. |  
        | 2. | Excludes the normal lead of 
        the suit bid by the defenders |  
        | 3. | Excludes the lead of a 
        trump |  
        | 4. | May exclude the lead of a 
        natural suit bid by defenders - leader must deduce situation based on 
        holdings and aggregate bidding |  
        | 5. | Often means the lead of 
        Dummy's first bid suit, depending on partnership agreements |  
        | 6. | May mean the lead of a 
        Spade (or highest suit not bid by opponents), depending on partnership 
        agreements |  Also see Lightner Game Double and
