If the seven is fourth best, i.e., from QJ87, then I'm winning the first trick cheaply and taking three heart tricks. If it's from a doubleton or singleton, even better. I can double-hook East out of his queen-jack and take four heart tricks. I play low from dummy. East plays the jack, and I win with the king. (The king is the right card. You would sometimes duck the ace but would almost never duck the king, so winning with the king conveys less information.)

There is some chance West led from Q87. But that's an unattractive lead, so I'll assume the lead is from shortness and RHO has the queen. That means I can take four heart tricks, three spade tricks, and a diamond. If I can take four club tricks, that makes twelve tricks in all.

I need to lead toward the queen-jack of clubs twice to pick up king fourth on my left. If I had entry problems, I would lead a low club now. But I don't, so I might as well cash the ace first in case RHO has a stiff king.

I cash the club ace--nine--three--deuce. Now six of clubs--ten--jack--king. East continues with the four of hearts. I finesse the ten, and it holds. I have the rest. Making six.

Plus 490 should be dead average. No other auction is conceivable, and the play was routine. But quite a few declarers managed to take only eleven tricks.

How? They began by playing a spade to dummy to lead the club queen. You can't take five clubs tricks no matter how the suit lies, so finessing East for the king never gains. And it loses if either opponent has a stiff king or if West has king fourth or fifth.

Still, the suit was friendly. So that mistake didn't matter. It was the next mistake that was fatal. If you lead the club queen, it holds, and you find yourself in this position:

You need to take two heart finesses to come to twelve tricks. Having squandered one of your spade entries, you must take one finesse now. Then you can drive the club king, run clubs, and finish with a second finesse. The declarers who reached this position, however, played another club and held themselves to eleven tricks.

Taking a heart finesse in this position is indeed dangerous. If it loses, a spade shift will kill the dummy, and you will lose the club suit. But we decided at trick one that the heart queen was onside. It's not clear to me whether these declarers failed to deduce at trick one that the heart queen was onside or whether they didn't notice that they were running out of entries. But, for whatever reason, playing this hand correctly was worth a generous 82%.
