I have a theoreticall question that i ve been some desoriented and i don´t know how to proceed. 

Suppose i´m the BB, and i defend against a minraise BTN of a though opponent. Flop K95r i check/call, turn J we both check. River 2.

On the river i usually try to think on a strategy that makes villain indiferent to call with a hand like Jx, which is my main concern of his range.

So here comes the theoreticall question. What if villain does not fold Jx ? What should we do ? 

A) Keep playing the same strategy (bluffs and value, staying balance), anyways he´s not winning money by calling with Jx on the long run.

B) Stop bluffing ? Remove the total, or some part of my bluffing range. I supposed this is a good explotative option, but im not sure that would be the best option against my nemesis. Against a nemesis, i want to still bluffing, or if im not he could start folding every time i bet.

C) Create an overbet strategy, looking for improve the EV of my strategy when villains calls ? Or maybe, i start getting some folds overbeting.
