Imagine this situation:

You're playing 200 bb deep and CO opens 2x a 35% range and u 3bet 6x from the BTN. CO calls.
flop came 5s6d7d. CO check and you Bet 40%pot. He calls.
the turn bings a 2c. CO checks, then due the fact of CO's range is capped in one pair hands BTN decides to bet 125%pot.
CO, even capped, should have a raising range there?

This question came to my mind when i realize that i always call, even with a very good hand. or fold, due the level off polarization of the oponent's range. For me sounds awkawrd raise this spot, once you'll never have value hands to go with your bluffs.
unless u start to check raise turn with TT, 99 and stuff like this, but i think you'll get crushed raising those. Exploitatively could be done raising only your bluffs vs oponentes who overbets too much, but into a GTO perspective, is doable ?

i'd love to hear some opinions about this.
