Ok I watched this video by a poker player that details what he thinks
Poker Barrel Bluffs
about bluffing and his poker player types. He's referring to how many streets a player will bluff at you based on how they play. He thinks:
A NIT fires one bluff ( e.g. a one-barrel bluff)
A TAG fires 2 bluffs (2 barrel bluff)
A LAG fires 3 bluffs (3 barrels - all the way to river)
A DONKEY fires Infinite (bet bet bet bet)
Now on the face of it, this seems well reasoned. But here's the problem. If you start thinking in terms of limits and constraints this may seem like a rationale idea. But here's the problem. If your opponent looks back at the history and sees you only call 2 streets then no matter what you do they are going to fire three. You have become predictable. Your predictability has become a weakness.
This is the kind of fixed frame thinking that will lead to people beating you.
Sometimes I bluff once. Sometimes I keep bluffing. If I think people are calling on the flop hoping I shut down on the river, then I will reraise them on the turn after I check.
By announcing how you play, no matter what your tendencies, you give your opponent more information.
