          Opening lead: DK
     The auction shown was not the actual auction but it is what
I think should be reasonable for the cards in this hand.  Two
clubs is a strong opening and two diamonds is waiting.  Two
hearts shows a suit and while South may want to show a second
negative by bidding three clubs, it is clearly right to show a
six card major suit.
     North now bids his second five card suit and South rebids
spades to show a six card suit.  North bids clubs again to
indicate he has at least five clubs and South raises to the club
game.  It should be clear to North at this point that while South
may not have much in the way of high card strength, his shape
should be enough to bring home twelve tricks.  To this end he
bids six spades, which ends the auction.  West leads the ace of
diamonds and South is able to ruff, draw trump and claim.
     Six clubs will make twelve tricks for plus 920 but six
spades will make thirteen tricks for plus 1010.
