Most of the time the people who bluff and end up wining know exactly how to carry themselves, the game is about trying to deceive and confuse your opponents so that they may think wrongly about your motives.
A very important move to bluff and that is why it is said that experience counts in poker. If you are beginner and bluffing you would be skeptical but experience people will never show or you cannot find out easily if they are bluffing or not. It is also a art which is developed over the time when you play it.
If you have good cards and you are also bluff master, no doubt you will win lot on money in poker games. If you have bluffing experience you will get good cards in every game because of bluffing. One of my friend is very good bluffer and I wonder how he knows the cards in my hands. He knows all the cards in other peoples hand. That why he mostly won the game.
