It's hard to advise you without more specifics. Try posting some hands that you are struggling with in Tournament HA.
I mix my game up quite a bit depending on my chip stack, position and the chip stacks of the other players.
You are obviously not struggling early in the game - but we need to know what is happening when you start losing the chips you have built up.
The only indication you give is that at times you bluff and it usually works. I can't really call anything I do "bluffing". That doesn't mean I won't play hands aggressively when I think I could be behind - but I don't think of it as bluffing
when I am using my position to win pots. Bluffing to me always makes me think of wild betting and taking shots at pots randomly from any position. (Especially in freerolls
). If that is what you do then that could be your problem. I see people play like that in freerolls all the time.
**my definition of bluffing is not official lol
