Both 6♠ by West and 6♥
by West can be defeated.
What are the exact North-South hands?
Against 6♠, South ruffs a diamond lead with the
eight-spot and cashes the ace of hearts.
Against 6♥, South trumps a diamond lead with the ace, then North scores a club ruff with the eight of hearts.
There is no other combination of cards that can defeat both contracts.
