Sometimes you can do it with strong hand but pretending you likely have weak hand. But it depends on opponents.I often wonder about players who go all in preflop,. Why are they doing it, are they trying to bluff everybody away, or what? They most likely have a fairly weak hand otherwise they would stay in the pot to gather up the cash when they won. However it is a good psychological bet as nobody wants to be out of the game.
Why not,if the premium cards.
