North-South were employing the European style of opening one diamond on all balanced 12 to 14-point hands, regardless of minor suit distribution. South opened the bidding with one diamond and rebid one no trump with no diamond suit and no spade stopper. Voilà!
The bidding seduced West into a club lead. Most of us would have done the same. South won this in hand with the 10 and led a low spade to dummy's nine, losing to the queen. East shifted to the jack of hearts, ducked all around. The low heart continuation was won by declarer with the king perforce, followed by a low spade to the jack. South cashed the ace of hearts in dummy and exited with dummy's last heart. East was forced to win and lead a diamond, as he had no cards left in any other suit.
The diamond shift ran to dummy's queen, and South crossed back to his hand with a diamond to the ace. West, who had discarded a club earlier, had to let go of a spade. The ace and another spade put him on lead and forced a club lead into declarer's ace-queen. That was nine tricks -— three clubs plus two in each of the other three suits — not to mention the satisfaction of having end-played both opponents on the same deal!
