One deal begat two game contracts

Mickey Hart, who is best known as a drummer for Grateful Dead, said, "In the beginning, there was noise. Noise begat rhythm, and rhythm begat everything else."

Today's deal begat two interesting game contracts, four spades in a nine-card fit and four hearts in an eight-card fit. First, let's look at four spades. (Tune in tomorrow for the discussion about four hearts.) After West leads the club queen to South's ace, what should declarer do?

Note North's rebid: Two spades was best. He might have gambled with one no-trump, treating the singleton king as if it were king-doubleton (not a bad plan), but two spades was still preferable. (He couldn't rebid two hearts, because that would have been a reverse and promised at least 17 points. Also, two diamonds would have been poor with such an unimpressive five-card suit.)
