If you have a good hand at poker and you want to stay for long time as compared to other poker tables, you should not let others know that you don’t want to fold. If they come to know about this, they will understand that you have a good hand and so they will fold leaving a tiny pot for you to win.
On the other hand if you have a bad hand while playing on the poker table, it is better to fold and you should seriously consider this. Whatever is the case and situation, do not let your opponents guess what is going on in your mind and this is important for your desire to win the game.
If you have an outstanding hand and you want to stay in the game and the other players come to know about that, they will immediately fold and leave a small pot for you on the poker table and that will be quite negligible in front of the value of your hands and you will not get the maximum benefit.
