When we declare in a notrump contract, we need to produce winners. We begin by counting our immediate winners, cards like Aces and Ace-Kings, that can be used to take a sure trick. We then turn our focus to how we can develop other cards into winners, called potential winners. The traditional methods for developing winners are Promotion, Length, and Finesse. These techniques are not certain to produce winners, but they give us a chance of producing additional tricks if lucky things happen for us. Here we look at each of these methods in detail to help us understand our options and determine when to make use of the different trick development techniques.
