9 handed 200bb ef'

Hero opens UTG 3bb with AdQh, UTG+1 3bet [polarized range] to 11.5bb, BTN cold calls. Hero calls [I didn't 4bet to maintain his weakest range, because he folds all of his air all the time].

flop [pot is 36bb] KhJs6s
Hero checks, Utg+1 bets 16bb, BTN calls, Hero calls.
Turn [pot is 84bb] Ah, Hero checks, UTG+1 bets 43.5bb, BTN folds, Hero calls
River [pot is 171bb] 6h, Hero cheks, UTG+1 shoves all in[121bb]. Hero? After announcing to table that I can't beat any value hand, he told me that my hand is AQ face-up... So we have a read that villain knows what we have for sure.

Well, I think he is betting his entire range on the flop, so my call there is pretty much standard, and the BTN is capped, so I don't expect him to show with a big hand on this flop that he is only calling with. On the turn my hand is clearly best, and I expect villain to fire again+I have redraw to the nuts [2 clean outs].

On the river I have to be right about 30% of the time. Villain is capable of bluffing the river for sure. I thought about shoving the turn, but no worst hand calls, but I guess moving villain of his equity is a good idea. So I want to understand if my thought process was right. If villain never bluffs the turn, but has a lot of worst hands then ours, we have to raise the turn with our hand, but if villain does bluff the river, we can just call down on any card. Am I right here, or you guys think I can find a fold on certain rivers?
