It seems the discussion this far applies most to when we have position on the loose player. (although maybe it isn't)

Is there something to add to the table conditions where we do not have position?

Let's put us in a situation where we are CO, and the loose passive guy is BTN. (the one that's a calling station postflop as well, not the flop folding type)
Blinds are tags/nits that at least are partly able to exploit a wide limping range of us.

My view;
I often turn into a preflop nit like 10/8 in this situation, or just move tables. While those are viable options imo, there seems to be a better way to handle it.
Also from a fundamental point of view I think there's room for opening up, instead of narrowing our range.

But really; opening up wide and not cbetting seems to be the one strategy not to use against this player, or is it? (I'm not sure)

- Should we just keep cbetten, but realise that we're cbetting for lighter value (like A high or bottom pair being for value)

- Would it be (more) profitable if we decide to lower our PFR size to 2 or 3 BB (assuming this makes the blinds exploit us way less often then if we limp) and cbet bluff way less often?
(some sort of fit-or-fold, but paying a bit bigger price then limping for the purpose of not being exploited by other players)

- Has anyone every tried a constant PFR size of 6+ BB in the mentioned situation?
