An opponent might not be pursuing that suit for their melds, for instance, if they discard several cards from that suit. This information enables you to either simply prevent your opponslots ioent from finishing their strategy or pick up those discarded cards if they fit into your own. Also, it's equally critical to be mindful of what you throw away. You risk losing if you discard valuable cards or cards that could aid an opponent in finishing their melds. To keep your own hand open for more plays, try to discard cards that are less likely to help others.
