When declaring the hand, it is important to remember the bidding.
The auction usually holds information that will help place the
opponents' high cards. Here is an example.

BIDDING: Over East's 2 bid,
South had the values for 2NT but was concerned about holding only one
spade stopper. A takeout double normally includes four cards in
the other major but South finally decided this was his best call.
This partnership uses the Lebensohl convention so North's response of 3
showed values. With a weaker hand, North would have bid 2NT
relaying his partner to 3 and he would then show a weak hand
by bidding 3. South bid 3NT hoping for
help in the spade suit.
PLAY: West led his
partner's suit and declarer saw he needed the diamond suit to come to
nine tricks. Remembering the
bidding, South realized the king of diamonds very likely to be
in the West hand. Accordingly, he rose with dummy's queen so that
East would not duck the first spade. East could do no more than
continue spades and declarer won the third round. It was now safe
to enter dummy and take the diamond finesse. Declarer ended with
nine tricks (1 spade, 2 hearts, 4 diamonds, and 2 clubs).
Note if declarer played low from dummy on the first trick, East would
insert the nine of spades. It would be essential for South to
duck this trick. By rising with the queen, declarer would win two
spade tricks if East failed to play his ace.
