    Trump Coup - An unusual  play tactic requiring declarer to 
reduce the number of trumps in hand to that of the threatening opponent holding 
the same number of trump.  The declarer cleverly plays winning tricks in a 
side suit and if the declarer's Right Hand Opponent ruffs, the declarer overruffs; otherwise the 
    declarer sluffs losers in side suits.  If the declarer sluffed losers on the side suit before reducing trump and the RHO refused to 
ruff, the declarer would have to ruff a card in dummy; then the declarer would 
become endplayed, having to lead a trump to one of RHO's higher trump cards. South ends up in a 
4H 
        contract.  West leads the DJ and the opponents' capture the first
        3 Diamond tricks, exitinging 
        with a Club.   South plays to Dummy's
        SA, then hoping to 
        finesse the HK but when Dummy's 
        HJ gets West's H10, South knows East has the
        HK 
(restricted choice) and the suit must be 4-1 
        in Hearts. Thus, East's HK cannot be finessed using brute force.  
        There must be a way... First, reduce East to 2 trump with last finesse
        H5 to H6, 
with East stubbornly ducking.

        J 9 |  |  South's only chance is to 
        promote Spades, forcing East to ruff sooner or later.  This 
        requires careful transportation using North's Club suit, having the 
        Dummy overtake South's Clubs three times, ruffing Spades twice to get 
        back to South's hand.    Here's one of several sequences that will 
        work:  CK to CA,
        S3 to H7,
        CJ to CQ,
        S4 to H8.  Now it's 
        show time...

  A Q 
   
  9 |  |  South makes the last entry 
        to Dummy's Club, 
C9 to C10.  
        Dummy leads a SJ, pinning 
        East's Hearts - a unique type of finesse.    As we witnessed, 
        critical elements are dummy transportation, shortening RHO's trump down 
        to 2, shortening declarer's trump to 2 also, and lack of any better 
        opportunity (since the plan requires several contingencies). |
