Contract: 4♥ by South
Opening lead: ♥9
Declarer takes east's heart queen with the ace and leads a diamond. Best defense is for west to grab the ace and lead another trump. Today, however, west plays low, giving you a chance for an overtrick.
After winning dummy's diamond king, there are three distinctively different lines of play to garner an eleventh trick. One of those options has two variations, depending upon what the defense does. Your mission is to find all four.
