This knowledge includes identifying patterns and predicting possible moves from opponents, going beyond merely understanding what makes a valid meld. Gamers should become acquainted with a variety of combinations, including sets (three or four cards of the same rank) and runs (three orummy play apkr more consecutive cards of the same suit). Players who are proficient in these combinations are better able to plan ahead and decide which cards to keep and discard. Players should also be very aware of the cards their opponents draw & discard. Seeing which cards are taken from the discard pile can reveal important information about an opponent's strategy and possible melds. Players can use this awareness to make strategic choices about their own gameplay, like whether to keep certain cards or to throw away potentially helpful cards to thwart an opponent's plans.
