Dummy's queen fetched the ace but South ruffed and drew trump, discarding two spades from the table. Declarer decided to take two heart finesses in search of a twelfth trick. Therefore, he continued with a heart to the ten which held the trick. A spade was discarded on the king of diamonds and followed by a diamond ruff. South played off two more clubs catching West in a triple squeeze. He was compelled to find a pitch from the king-jack of hearts, ten of diamonds and the king-ten of spades. He elected to throw a spade as dummy parted with the now useless nine of diamonds. The play of the ace of spades felled the king and an overtrick was home, N-S +1390.
South had underbid by a considerable margin since he was virtually assured of nine tricks but he had learned that partner held an opening bid. He, therefore, continued with four clubs as a slam try and advanced to the minor suit slam when North cue bid four hearts disclosing the ace. 6NT could come home even if East starts with a spade. North must hop with the ace and take the double finesse in hearts for twelve tricks.
