There are two possibilities; the queen of diamond can be on either hands.
When by west as simple as a finesse when by east a trumph-squeeze that seldom
works. (East has to hold the queen and the jack of clubs too)


Firstly: cash the ace of spades and then trumph three times. (if needed)
Secondly: Give the opponents their spade.
After this trumph one round. 




            x  - A T
                 K 9
                 
                                  - - Q Q  
(immaterial)                          x J          
                                      x


            -  x J  -
               x x  
                 x
A trumph now squeezes east (could as well be west). You discard the xs.
If East (West) discards a diamond the game is played and you got your tricks by
topping the diamond and a ruff to the Jd on the hand. If he discards a club
a diamond is playd followed by a club-ruff. The diamond king works as an entry
to the (now) high Tc

Anyway I'm not shore that this is the best play if nothing in the bidding
indicates that east holds the Qd. It would in other case be a real show-up-
squeeze.

I agree mostly with the play in the article but I'm afraid that I wouldn't
rely on my opponents playing wrong. With such an attitude the right play is
not allways the best.

The contract is home using a trumph-squeeze when East holds:
Qd and QJc
Qd and more then three clubs (a combined trumph- and clash-squeeze) (or is 
it called guard-squeeze)
either opponent QJd double (if one guess right)
trivial: DJc double         
               (* might be quite near 50% *)

here the combined trumph and clash-squeeze:
  
                  - - A T
                      K 9
                      T
x - x Q                             - - Q J
x   x                                   x x
                                        x

                  - x J -
                    x x
                      x

A finesse is eventhough more likely, becouse it is not possible to get a 
complete cardreading on east, and he can (and every routined player should)
falsecard and in the squeeze-trick hold something like - - Qx Jxx. When 
he now discards a club on the second last trumph you are likely to
take out the clubs.
