Unlucky Louie showed up at the club with his wrist in a cast.
"What happened?" I asked.
"The power went off at my house last night," Louie said. "If you ever wonder where your kid lost her roller skates, try walking around the house in the dark."
When Louie was declarer at 6NT, he had more trouble finding the queen of diamonds than his child's skates. He won the first club with the ace, led a diamond to his ace and returned the jack. East got the queen, and Louie had only 11 tricks.
Could you find the missing queen?
Louie should delay his guess. He takes the ace of spades at Trick Two and leads a low spade. West wins and leads another club to dummy, and Louie next takes the king and the 13th spade, three hearts and the king of clubs, on which East discards.
After 10 tricks, Louie has a complete count. West had six clubs, three spades and three hearts, hence one diamond. So Louie leads a diamond to the king and finesses confidently with his jack.
You hold: A K 8 4 T A 9 6 K 9 5 2 A Q. You open 2NT, your partner responds three clubs (Stayman), you bid three spades and he tries 4NT. What do you say?
A: Is partner's 4NT the Blackwood convention (you must bid five spades), or is it a "quantitative" raise to try for 6NT (you must pass)? With no prior agreement, I would treat 4NT as Blackwood. What is certain is that an experienced partnership will have discussed the matter.
