If you're not in the best contract, even good declarer play isn't
enough. Here's a good example.

BIDDING: North's cue bid
of 3 asked South to bid 3NT with a
heart stopper. Not realizing the value of the queen opposite
JXX, South declined and North raised to the club game.
PLAY: After winning the first two heart tricks, West
continued with a third round. The first reason was to allow
partner to ruff out dummy's jack, and the second was the possibility
partner would ruff with an honor and promote the ten of clubs.
Declarer was now stuck with what
appeared to be a losing trick in diamonds. After drawing three
rounds of trumps, he realized that West had started with nine cards in
hearts and clubs and therefore would likely be short in the other two
suits. With a squeeze against East in mind, declarer next played
three rounds of spades ruffing in hand. Now he knew West held
only two diamonds so he tightened the noose around East. On the
last trump, East had to discard from J and Q86
while dummy held 7 and A9 and
declarer held K102. A discard from either
suit would give declarer his eleventh trick.
This was a well played hand by declarer. Unfortunately, several
pairs were in 3NT also making eleven tricks for a better
score. In most of those cases, South opened the bidding 1NT and
the higher scoring game was quickly reached.
