If you have strong cards like KT or AJ then you should be willing to play these hands preflop even when there are only a few players in the pot. For the rest of the hands you should just fold them and not waste money. The preflop decisions are very important but that is just a part of the whole story. There are three rounds after the flop and the decisions that you would need to make at every stage are important.
