While defense can be difficult, sometimes it's just a matter of
counting to thirteen. Take a look at this simple math problem.

BIDDING: South's 1NT
showed 12-14 high card points and became the final contract when
the
vulnerability made West too nervous to get involved.
PLAY: West led a low
diamond and declarer mis-guessed by playing the ten from dummy.
Declarer won
the jack with the ace and led a low heart to the queen and ace.
Next he led a low heart to his jack and the king. West cashed the
diamond king and then the nine. On the third diamond, East
discarded the nine of clubs. This partnership uses "upside-down'"
attitude signals so the nine said "I don't have anything in
clubs". West quickly added up declarer's known high card
points: 1 in hearts, 4 in diamonds, and 8 in clubs. That
meant East must hold both the king and queen of spades. It was
then easy for West to shift to the ace, jack, and ten of spades to beat
the contract two tricks. As you saw, proper defense involved
nothing more that communication and simple math.
