Take your time when on defense
Saint Augustine, who died in A.D. 430, said, “Patience is the companion of wisdom.”
Many inexperienced defenders lack patience when it comes to taking tricks. “Win now and think later” is a prevalent attitude, often with costly consequences. This deal is an example; but first, what do you think of the auction? North’s two-heart response was natural and promised in principle at least eight points. North thought about opening two hearts, planning to introduce his clubs on the next round if it seemed expedient. However, he was in the second position, when one prefers to have a textbook hand for a preemptive opening. South, with only 15 high-card points, was light for her two-club opening, but she had only a three-loser hand, and owning spades gave her control over the auction. After that, the auction was sensible, North correctly upgrading his hand.
West had a tough lead. I think I would have selected the heart king, or perhaps the club jack. The diamond three would have been tempting too, but would have been fatal here. The trump lead risked costing partner a trick in the suit, but was safe this time.
South played three rounds of spades, discarding hearts from the board and putting East in. To defeat the contract, East had to shift to a heart or a low diamond, but chose to cash the diamond ace. Then he cashed the club ace, and declarer accurately threw her king. Now South could get to the board with the club queen and cash the heart ace to discard her diamond 10.
