Gino's Suggestion and a Short Explanation
The plan: Promote hearts. Then draw trump, finishing in North’s hand with many heart winners.
Win with the ♦A. Cross to dummy’s ♠A/K. Ruff a heart in your hand (ruff high). Play a high spade from hand. Play the third round of spades to dummy’s remaining ♠A/K.
Hope to make 11 or 12 tricks when both suits, hearts and spades, break 3-2.
