Playing a club pairs event, I had the rare opportunity to execute a very nice coup, after an auction which led us to the top spot, the only pair to manage it.
Here are the cards:

                 ♠  A 6
                  ♥  9 6 2
                  ♦  A K Q 8 5
                  ♣  Q 6 5

 

♠  9 3
♥  8 4
♦  J 10 7 6
♣  K J 9 8 7

♠  5 4 2
♥  K J 10 7 5 3
♦  4
♣  10 4 3

 

♠  K Q J 10 8 7
♥  A Q
♦  9 3 2
♣  A 2

 

The bidding went:

 

The eight of hearts lead went to the king and ace, and after three rounds of spades - West pitching a club and dummy letting go a club - I cashed the AK of diamonds.  The news was not so bad: with West guarding diamonds, and East having to take care of dummy's nine of hearts, the layout was perfect for a rare form of double squeeze.

After having re-entered my hand with the ace of hearts, I ran spades to reach this position:

                 ♠ 
                  ♥  9
                  ♦  Q 8
                  ♣  Q

 

♠ 
♥ 
♦  J 10 
♣  K J

♠ 
♥  K 
♦ 
♣  10 4 3

♠  7
♥ 
♦  2
♣  A 2

 

When I tabled my last spade West had to discard a club, so dummy pitched a diamond and East a club, leaving:

                 ♠ 
                  ♥  9
                  ♦  Q
                  ♣  Q

♠ 
♥ 
♦  J 10 
♣  K

♠ 
♥  K 
♦ 
♣  10 4

 

♠ 
♥ 
♦  2
♣  A 2

 

I followed with a diamond to dummy's queen, and East got caught in a rounded suits squeeze. Did you notice that in the end it doesn't matter whether it is the queen of clubs held, or the three, but it is relevant at the beginning: without it, the defenders can lead the suit breaking the communications for the double squeeze (tip for the defenders: whenever you can see that a double squeeze is impending, attack the double menace).
