Focusing on completing runs first is a good tactic because they can be simpler to form with consecutive ranks & frequently require fewer cards than sets. A rummy earningplayer with a 5 & 6 of hearts, for instance, could quickly meld those cards if they drew a 7 of hearts to complete a run. Paying close attention to what your opponents discard is another crucial tactic. A player may be working toward a particular set or run if they discard a card that another player picks up.
