An indication that an opponent is aiming for a particular meld could be given, for example, if they routinely remove cards from the discard pile that you have already discarded. You can modify your approach and possibly foil trummy new appheir plans by remaining aware of these cues. In rummy, even seasoned players can make common mistakes that reduce their chances of winning. Keeping high-value cards for too long in the hopes of creating a meld is a common mistake. An opponent declaring before you have a chance to make good use of those cards could make this tactic backfire. Rather, it is usually better to eliminate high-value cards early on if they don't support your current plan.
