To strengthen your hand, finish your sets and runs, & reduce the possibility that your opponents will take advantage of your discards, you should strategically discard & draw caupi ludords. Prioritizing the removal of valuable cards that are unlikely to be necessary for finishing your sets and runs is a good way to engage in strategic discarding. You can lower your chances of losing points if your opponents declare their hands before you've had a chance to lay down your own sets and runs by discarding these cards early in the game.
