“the way, when I showed this to Leslie, I used real cards, not a bridge diagram. If you find it difficult to follow the diagrams, try using a real deck. For the first hand, you can also try dealing East the king of spades instead of West, and you will see why the finesse won't work. A finesse is a cool play that allows you to win two tricks with the ace and queen of a suit, even though one of your opponents holds the king. It has a 50 percent chance of success, depending on which one of your opponents holds that king.”
