Third Answer
The play has proceeded: seven of diamonds (three, Ace, six); Jack of hearts (Ace, three, five); nine of spades (eight, four, Queen); five of diamonds (King, eight, four). Now you lead the seven of spades and LHO plays the five. What’s your plan?


West’s high-low in spades might be a false-card from original K85 and might be a true card from 85 doubleton. We recommend that you play the Ace and then ruff a spade low; if West over-ruffs, you can hope that it’s from a natural trump trick.
You declare as suggested, winning the Ace of spades and ruffing a spade. East over-ruffs with the ten and returns the Jack of diamonds which you ruff. When you cash the King of hearts West follows with the Queen as expected. Which opponent do you think has the Ace of clubs?
