Do you think this bluff is ok?
When I analyzed it I noticed that I only have 6 Valuecombos (A2s,22,55) so I'm overbluffing if I bet all my 65s and all my A5s but how do you control your frequencies like that.

Do you always have to be fully aware of your range and count combos?
The bluff is debatable. My approach is to have bluffs in every situation, especially in situations where most people don't bluff.
My reason for that is that there were countless situations in which I have gotten folds where I thought no one would ever fold there, so at least I am covering these areas where people may fold too much exploitively for the sacrifice of losing a stack here and there because I either get herocalled or I run into the nuts.

By the way if I wanted to introduce a bluffing range on the river, which hands would I want to make indifferent? My thought process was that I probably want to make his overpairs indifferent so I want to polarize between hands that can beat overpairs (trips,FH) and hands with blockers to his nutted hands (5x).

But since some of my valuehands will lose to the top of his valuerange.. will I lose money in the longrun then? or is only the bluffcatcher part relevant?

And how much bluffs should we be betting OTF? Does it make sense to bet an overpair like 77 or 88 into three people a % of the time?
Because then it would make sense to mix your overpairs and bet them a % of the time so that you can generate more valuecombos on a various amount of rundowns because you don't really want to skew your ranges too hard towards value or bluff on some runouts that would allow him to explo fold based on range creation.
This would allow us to bet more bluffs on some rundowns to keep villain indifferent.

Ok but this is nl2 so I am not sure if I can apply this theory somehow :I ??
I can imagine that there are people who will snap me OTR with JJ, thinking it's good.

Ideas, thoughts, suggestions pls?
