The Encyclopedia of Bridge has a list of all suit combinations and how to play them depending on how many tricks you need. A good player does not need to memorize this, and can usually deduce the correct play at the table. However, it is worthwhile to study the suit combinations table. Also remember that the optimal play in a suit may not be best in the context of the entire hand.

The correct play is to win the Ace of Diamonds and to continue with the Ace of Spades followed by the Queen. Even if the King is with South, declarer loses 3 tricks only, if trumps are 3-2. And if trumps are 4-1 the game will still make
if the King of Spades is sitting with North. The advantage of the losing trump
finesse to the losing normal finesse is the gain of tempo.Suit Combinations
