Deception is basically a matter of pretending to hold a hand that is different from the one you actually hold.  Look at the following situation.

 West S - J 7 4 H - 9 8 7 6 5 D - J 9 8 6 C - K North S - Q 8 H - J 3 D - A K 5 C - J 7 6 5 4 3 South S - K 10 9 6 5 3 H - A 2 D - Q 10 2 C - A 2 East S - A 2 H - K Q 10 4 D - 7 4 3 C - Q 10 9 8

The contract is four spades in the south and West leads the heart nine.  Declarer cannot avoid losing a heart, a club, and the ace of trumps.  This means that to make the contract he must guess the location of the spade jack.  Life would be much easier if one of the opponents would lead trump.  So declarer decides to play like a man who is anxious to ruff a heart in dummy.  He wins the opening lead with the ace and promptly returns a heart.  East wins dummy's jack with the queen and will very likely play the ace and another spade to prevent any ruffs.  This eliminates the trump quess, and the contract is home.

Of cource if East held something like A J x of spades, he wouldn't make the obvious trump return, and declarer would still have to guess the location of the jack himself.  But in this case, the very fact that East was reluctant to lead a trump would probably guide declarer to the winning guess.
