DEVIL'S COUP (Coup d' Etouffement = death by suffocation)
 

This is a very rare type of throw-in Coup that can be done only in suit contract to capture opponent King of Trump that appears to be impossible be captured like in this hand bellow:
             North      N-S is playing 6
             A32       and the lead was 9
             A32       As we can see N-S has 2 losers: K and 3th
             8765
             AK2 
West                   East
K654                   7           
765                     QJ1098 
432                     QJ10     
987                     10654      The Play by South:               
             South       After South make Q he finesse Spades       
           QJ1098    two times then play AK Clubs and AK        
           K4            Hearts and ruff a Heart.
           AK9      Finally South play AK Diamonds and give
           QJ3       the last Diamonds to East.

Final of two cards where East must play is:
              North
              A
              8
West              East     now East must play  Q or 10
K6                 Q       and South will ruff with 9 and if
                       10     West play the K then North make
             South           the A, if West play 6 then South
              109            makes 9 and the last trick will be A!


================================================

Another very rare situation is the play of a Grand Slam where is missing QJ854 in the trump suit.  Of course this can be done if QJ are second but this is not the best chance and the Brazilian bridge's champion Nelson Martins Ferreira play it in 1974 considering trump 3-2 and honors divided in a overbid contract of 7:
North = Synésio
 K73             the lead was J
 AKQ2
 109754
 A 
======
South = Nelson
A10942 
5
 A32
 KQJ9

So declarer must search for a final of 3 cards where:
      
           K7
           x   
Hx         Hxx
 x            -
           A109
          -
In this position North play his loser Diamonds and if East ruff low then South cover with 9 and claim, but if East ruff with an honor then South cover with the A and must finesse West honor playing the 10 to let run if West play low Spades.

Nelson knew the best chance to play in this configuration and play it quickly discarding in the top Hearts 2 losers Diamonds and ruffed the last Hearts that was 4-4. Now he Plays Ace Diamonds and go to dummy in Ace Clubs to play Diamonds and ruff. Then he plays 2 top Clubs and ruff the last Clubs hopping for Clubs 4-4. Finally he was in the desiraded configuration and when East do not served Diamonds he only need honors divided to have success.
