Bluffing is a fundamental component of many card games, including rummy. Even though subtle deception isn't as obvious as it is in poker, it can have a big impact on how a Rummy game turns out. By throwing away c777 appards that could give opponents the wrong idea about their intentions, players can use bluffing strategies. For instance, opponents might think they are pursuing a particular combination when they are not if a player discards a card that appears to be essential for finishing a meld. Also, by periodically selecting cards from the discard pile that don't seem immediately useful, players can engender a sense of uncertainty.
