Second Answer
The opening lead is the seven of diamonds (three, Ace, six); back the Jack of hearts (Ace, three, five).
What now? You may need to ruff a club in the dummy, so it’s probably best not to play another round of trumps now..
Say that you lead the nine of spades (eight, four, Queen). Back the five of diamonds (King, eight, four). Now you lead the seven of spades and LHO plays the five.
What’s your plan?
