Defense can be difficult but sometimes just a little reasoning will
solve the problem. Take a look at this example.

BIDDING: After a routine
opening bid, when South's 1 overcall came back around, East
made a re-opening double. This did not show extra values but was
necessary in case West held a spade stack and wanted to defend.
It is an important that partnerships who use the negative double
remember the importance of this. South's redouble showed a
maximum overcall and the auction quickly ended at the two-level.
PLAY: The opening lead was a diamond followed by a second
one ruffed by declarer. South saw the contract was in no danger
but this was a pairs event so he looked for overtricks. His loser
count was one spade, one diamond, and two possible hearts. The
bidding told him that at least one of the heart honors was on his right
but the king of clubs was the only obvious entry to dummy. To
solve this dilemma, he led the spade queen from his hand. East
couldn't wait to win with his ace and lead another diamond.
Declarer ruffed, led a spade to dummy's jack, and followed with a low
heart to his ten. West won and switched to clubs but South won
this in dummy and led another heart to his jack. He now had ten
tricks.
You no doubt noticed that East must duck the first spade lead in order
to limit declarer's access to dummy. With only one entry, South
must lose a second heart trick. When this hand was played in a
local game, one N/S pair bid and made 4, one went
+500 defending, six made ten tricks in a spade part score, and only
five pairs held South to nine tricks in spades. As we've seen,
without an unlikely heart opening lead, South should be held to nine
tricks. It isn't that difficult.
