This deal was played on BBO by my friend David Berkowitz with his student. Playing matchpoints, as South (nobody vulnerable), he held:

AJ
K1087
KQ86
K65.

RHO opened 1 and David overcalled 1NT, raised to 3NT. The 3 was led and he saw:

9832 A92 A92 Q42
AJ K1087 KQ86 K65

There aren't 9 top tricks, but there is potential for maybe four diamonds (with this lead and East's opening 1 bid) and maybe three hearts. Along with one in each black suit that would be 9.

David played the 9 from dummy and won East's J with the K.

He played a heart to the ace and ran the 9. Bad news. It lost to West's J.

Back came the 10. Now what?

The title "Rand McNally" (for anyone under 35) refers to the map company. David had a roadmap of the opponent's cards. East had opened 1 and West led a low diamond then the 10. So, diamonds had to be 3-3. Since East, playing standard, had opened 1 with only three of them, he had to be exactly 4=4=3=2.

Accordingly, David won the A and played a club to the king and ducked a club. This was the real deal:

Vul: East Dlr: None	9832  A92  A92  Q42
654  J4  1043  J9873		KQ107  Q653  J75  A10
	AJ  K1087  KQ86  K65

Never mind taking nine tricks; David had 10! He was able to later enter dummy with the Q to take the marked heart finesse. He took one spade, three hearts, four diamonds and two clubs for a top board.
