The Ace is the most powerful card in each suit. It almost always wins a trick (especially in a notrump contract), but the Ace does much more than simply win one trick. The Ace controls the suit. When we hold the Ace of a suit, we get to not only win a trick in that suit, we get to decide when we take our trick and gain the lead. Holding the Ace gives us the power to choose how the play is going to go. The Ace can also be used to develop additional tricks -- capture the opponents’ honors and promote our honors or develop our little cards into winners by helping us establish our long suits.
