Suit management is more than just
finessing. You must be able to look at the entire hand and not
just the suit you are about to play. Here is an instructive
example.

BIDDING: North held a poor collection of cards but they
included twelve high card points and he felt obligated to open 1.
South had an easy jump to 4 after North's raise.
PLAY: West led the jack
of clubs and declarer was in trouble. The defenders took the
first two club tricks followed by the ace of diamonds. Declarer
won the second diamond in dummy and had to find the king of spades in
the East hand. Obviously the spade finesse must be taken but what
card should declarer lead from dummy? The correct card should be
a low spade to protect against the singleton king in the East
hand. However, if there are no more entries to dummy, declarer
must play a high spade to stay in the North hand if East fails to play
the king.
In a local duplicate game, eight pairs reached the contract of 4
and four of them failed by one trick because they led a high
spade. That nine of spades is a very valuable card.
