If your partner has had the original lead, and you have taken a trick, either make your high cards or
LEAD UP TO WEAKNESS
Weakness means no high cards, and leading up to, is making a person play fourth in hand to a trick. By leading a suit in which dummy has weak cards, you may enable your partner to win a trick cheaply. Whenever the dummy hand is on your right you should take this advantage of its weakness. It is sometimes good play to lead a card higher than the dummy's best. This, if the card you lead is not covered, gives your partner a chance to pass the trick.
