What is the purpose of an opening lead?
In a suit contract, our main goal is short-term - we are trying to produce immediate tricks for our side. In a Notrump contact, our general goal is long-term - we are willing to take some early losses (give up tricks) in order to set up several tricks for us later in the hand. In the money world we should think of a Short-term vs. Long-term investment. The same situation applies to differentiating between leads in a suit verses a NT contract. Let us see how we should set about which card to lead?
