A lead problem from a recent online league match.
Love All. IMPs Dealer South
After a long and complicated two over one auction you find yourself on lead against a grand slam.
Two diamonds was game forcing, four notrump was Roman Keycard Blackwood for hearts. Five clubs showed one key card and five diamonds asked about the queen of hearts, six diamonds showed the heart queen and the king of diamonds.
What do you lead?
South has long hearts and clearly the black suit aces, so your best chance is that South has a singleton diamond and that you can cut out the diamond suit in dummy by leading one. The full deal is below.
