It's nice to have the right tools to get to the best contract.
Take a look at a hand where many pairs missed a good game contract.

BIDDING: West had a good
weak two bid and North made a takeout double. South bid 3 and it was up
to North to decide if his partner held any high cards. After all,
South was forced to make a call and might not have a high card in his
hand. This pair uses the lebensohl convention so South's bid
showed 7-10 points. With fewer, South would have bid 2NT asking
North to bid 3 which South would have
passed. With more than 10 points, South would have made a
stronger bid ensuring the partnership reached game. Knowing game
was possible, North next cue bid hearts asking South if he had a
stopper and South continued on to game in notrump.
PLAY: The auction told
West that declarer held the heart king so he decided to try to find an
entry to his partner's hand in order for a heart to be led through
declarer. He tried the eight of spades and declarer stopped to
analyze the hand. Since a heart wasn't led, declarer felt it
unlikely that West held an outside entry. That meant both black
kings were probably in the East hand so declarer played the ace of
spades at trick one. He followed with the queen of clubs and
quickly wrapped up eleven tricks (1 spade, 4 diamonds, and 6
clubs).
I recommend you review the lebensohl convention with your partner.
