Dont bluff just for the sake of bluffing
Many players understand that bluffing is a part of poker, but not exactly how or when to bluff. There's is no rule that you have to bluff a certain amount or even at all. But many players feel like they've haven’t won unless they've tried a poker bluff.
But remember bluffs only work in certain situations & against certain people. If you know a player always calls to the showdown, it is literally impossible to bluff that player. It's better never to bluff than to bluff “just to bluff.”
