Fourth 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). Next the seven of spades (five, Ace, deuce) and six of spades (three, ruff deuce, over-ruff ten). West returns the Jack of diamonds which you ruff. When you cash the King of hearts the Queen falls from West as expected. Which opponent do you think has the Ace of clubs?
West had nothing in spades, Q105 in hearts, and appears to have only the Jack in diamonds. For the one notrump call, West really should have the Ace of clubs. Lead a club and, if West plays low, put up the King.
