Discarding cards that could give opponents the impression that you are aiming for a specific set or run while actually pursuing a different combination is a useful tactic. Tossing away a heart card while collecting hrummy gold real cashearts, for example, could give the impression that you are not interested in that suit. When it comes to rummy bluffing, timing is essential. When you bluff at the right moment, you can surprise your opponent and make them make poor choices because they thought you had a bad hand. But it's important to find a balance because if you bluff too frequently or too forcefully, more seasoned players might notice & modify their tactics.
