I play alot of cash games so bluffing is a thing I do alot. The POWER of betting is huge in cash games. Tournament play you can be more patient in the beginning and pick your spots. Bluffing is huge later in tournament play when the blinds start to climb. Bluffing is a huge part of my game. People will never know if I am bluffing or not. In the 5 years I have played poker I have never shown anyone my cards and I never will. If you want to see my cards you have to pay to see them.
