Discarding high-value cards when you are certain they don't add to your melds is a crucial piece of advice. If your opponent declares slots that pay real cashbefore you do, high-value cards can dramatically raise your score, so it's best to reduce their possible influence on your final score. The timing is key. For example, think about discarding a King or Queen early in the game if you don't plan to form a meld with them.
