In 6♠ on a trump lead, win the ♠8, cross to the ♦A and lead a low heart. If East rises with the ace, you have 12 tricks. If East plays low and the queen loses to the ace, your best bet for 12 tricks is the heart finesse. If the queen holds, play the ♦K Q, discarding dummy’s remaining hearts, and ruff a heart with the ♠9. It is unlikely either opponent has a singleton heart. West didn’t lead one, and East didn’t double either of the artificial heart responses with a likely five hearts headed by the A–J.
Assuming both follow to the second heart, return to your hand with the ♠A. If spades are 2–2 or West has three spades, run the ♣10 (or ♣Q) into East. If East has fewer than four hearts, he is endplayed. If he has four and exits with a heart, you can still take a second club finesse.
If East has three spades, ruff a second heart high. If hearts are 3–3, you have a spade entry to your hand to discard a club on the fourth heart. If hearts are not 3–3, lead a low club from dummy, and if East plays low, use your magnificent table presence to make the winning club play. If table presence doesn’t work, you still have an entry to take a second club finesse.
