If there is no bluff in your game you will rarely make it to a final table, you can't just depend on the cards that will hit the table, but if you're going to tell a story, it has to be told well. As I only play micro tournaments, it's very difficult to pass a bluff, guys call everything, but bluffing is part of the game.
People I believe worry too much about bluffing to be honest. They are concerned they need to bluff a lot or they feel others are bluffing to much. Bluffing is a art form in my opinion. To make a good bluff you need to bet a lot of chips to scare off the person or tell a story that makes the other player fold. The story must make sense to get the other player to fold a good hand.
depends on the flop and what cards i'm holding if my cards block somethings there's a higher chance of me bluffing than blocking nothing but if i can see a small spot to bluff with bad cards aswell it can be on the river
Semi-bluffing is much better than pure bluffing and the situation to pull of a pure bluff occurs
after missing your draws and you feel the other player missed theirs too or the river is a scare card for their range.
