Bluffing in my opinion is and advanced move. You need to know if the other player has enough discipline to fold, the hand needs to make sense, and the bluff should never be overkill. I bluff like 70% of flops, and I shoot two barrel if I see hesitation that is genuine on the flop. Though some player don't like being ran over by me at the table. I'v been called all in in MTT with ace high multiple times.
