One skill that can significantly impact your success in Rummy is knowing when to fold and when to hold onto specific cards. Keeping valuable cards might seem like a good idea at first, but if they aren't helping form melds or aren't likely to do santtaso anytime soon, it might be better to let them go. The secret is to check your hand frequently to see if any cards are impeding your ability to meld all of your cards. It might be time to think about getting rid of some high-value cards in favor of more practical ones if you find yourself holding onto several of them without any obvious way to combine them. On the other hand, there are situations in which both offensive & defensive tactics can benefit from holding onto particular cards.
