I was wondering if someone could help me out here. Im confused with what hands we should be bluffing with when the turn brings no straight or backdoor potential like Q727.

So normally i would cbet with most of my flopped draws and backdoor stuff on the flop but when i get this 7 turn card and the boards still rainbow i have no bluffs in my range. So i was wondering if i should start betting all combos of JTo on the flop seen as i can turn an OESD but that looks like a pretty poor turn barrel even if it does block some Qx.

Even on a flop like J44 when i turn a flush draw and a OESD when we have 65s on a 7 turn i still don't have enough bluffs with all my flush draws as well so i was wondering if i should be barreling off on some run outs with either AK/AQ/KQ.

After looking at my range on various turns and river cards i noticed if i decided to do it with enough combos of 1 of those holding then my range would be messed up if i had rivered a pair. Is there any vids on here about this or is there anyone kind enough to give me an idea of what i should be doing here?
