Ok, villain is 24/20 reg, 7% overall 3bet but felt he was tilted here because I had just uber coolered him, so felt he had like a 15%-ish squeezing range here.

I think the river kinda plays itself after I take this line, but I wanted to get opinions on the turn really.

Is there such a concept as 'betting to avoid getting bluffed'? Because that's what this turn bet felt like, as well as for basic protection and some value, and also keeping my range wide for rivers such as these.

I'm 'afraid' (not afraid, but you know what I mean) of getting bet check betted into on the river by a decent range on cards such as Q K A. We could of course argue that we could check back QJ KJ AJ on the turn such that we're protected on the river, but I still don't feel like it's enough combos and also many of those hands would rather bet turn, leaving river range particularly weak.

Cliffs of the post are, should we even have a checking range on the turn at all, and what do we think of my size?
