A common mistake is keeping high-point cards for too long. If another player goes out before you can play these cards, it could backfire even though it might seem wise to wait for the ideal time to meld them. It's usually better to focus on meslots indlding lower-point cards early in the game while watching for possible high-point combinations. Failing to observe opponents' discards is another error. Missed opportunities to block their strategies or take advantage of their weaknesses may result from failing to notice what others are picking up or discarding. For instance, you can gather those cards without worrying about interference if your opponent discards multiple spades, which might mean they are not attempting a spade run.
