Guarding a Suit
Taking tricks with small cards is an important part of Declarer’s plan for making their contract. As a Defender, it is our job to do everything we can to stop that from happening. That means that suits that have potential winners, threat cards, must not be allowed to grow up into winners. We attempt to prevent this from happening by covering an honor with an honor (to prevent promotion) and by holding onto our cards in the opponent’s long suits – called guarding the suit
