{

Consider this end position.  West declares, with the lead in dummy.  West has
all the tricks, but one.  Whenever this is the case, consider a squeeze.  While
a club finesse could produce the extra trick, suppose you suspect North of
harboring the \CQ.  For a simple squeeze to function, one opponent must be busy
in (guard) two suits.

Switch the North and South hands, and playing off all the major suit winners
would squeeze South, because West will discard after seeing South's discards. 
West must read the position correctly; cashing the ace of clubs before the
majors would solve that problem:  if you don't see the \CQ by the last winner,
discard the \CJ.  However, that won't squeeze North, who discards after South. 
Try it!

Dummy has a great card, the \D10, which we can use as the diamond threat.  Cash
the \DA, then run the major suit winners, discarding \DJ6 from hand.  Now the
squeeze operates automatically, if either opponent holds all of the \DKQ and
the \CQ.  Once the \DA is cashed, there is no guessing, when the squeeze is
working.  The end position will be

     \D                   \D 10\n
     \C A J            \C 5

Neither opponent (North here) can retain both \CQx and a diamond honor.  If the
\D10 is good, cash it.  If not, lead to the \CA and fell the queen.

{

South wins the opening lead of the \S5 (West dropping the jack) and returns the
\S7, won by West with the \SK.  West leads a sneaky \HJ, trying to avoid an
apparent spade ruff.  When this holds, another round of hearts clears trumps. 
North leads the \C3.  Declarer stops to consider.  With the minor suit aces,
dummy is good, with two losers.  After calling for the \C6, West ducks South's
\CK smoothly <i>to rectify the</i> <i>count</i> for what I call a <i>silly squeeze</i>.  Your garden
variety squeeze can only gain one trick.  To have any chance for such a squeeze
to work, you must have only one loser.  A silly squeeze meets all the
requirements for a real squeeze, but the threats are dubious.  When defenders
come under pressure, they sometimes make mistakes in discarding.

Run the silly squeeze just like the real squeeze.  Cash the \DA (Vienna Coup),
to establish the \D9 as a threat.  Then rattle off the major suit winners,
discarding the \D 10 6, and reducing to:

     \D                   \D 9\n
     \C A 5            \C J

If the \D9 is good, cash it.  Otherwise, lead to the \CA and see if the 5 is
good.  Guess what?  Both opponents kept diamonds, and it <i>is</i> good!
