Watch out for and eliminate losers

Ogden Nash said, "A family is a unit composed not only of children but of men, women, an occasional animal and the common cold."

A bridge contract is a unit composed not only of tricks but also bidding, declarer play, defense, winners and losers. In today's deal, South is in four spades. What happens after West leads the spade king?

Note that North might raise one heart to two hearts with only three-card support. If he has a minimum opening with 1-3-5-4 distribution, a rebid of two hearts is preferable to two clubs. So South's jump to four hearts promises at least a five-card suit. With only four hearts, he should make a different rebid, perhaps three no-trump with stoppers in the unbid suits, or in one of the other three suits.
