            (a) A weak two-bid

   Zia opened with a slightly frisky weak two-bid, and it helped Helgemo read the distribution. After the DK, a trump, a club to the Larry Cohen's ace and another trump, Helgemo won in the dummy and cashed the CK, discarding a diamond from hand. He ruffed a club in hand, cashed the SA, ruffed a spade in the dummy and called for the CJ. When Zia covered with
the queen, Helgemo didn't ruff. Instead, he discarded his last diamond, endplaying Zia. Before Zia could exit with a low diamond, Helgemo showed his cards, claiming ten tricks.
