Interesting spot 5knl good draw

Villain is a player i've never seen before that i had been playing for about 45 hands. He seems real aggro and has reggy like stats. One of the first hands we played i raised q7o, checked it back on a Q9x two tone flop and called down turn and river blanks, he had total air no draw. He 3-bet pretty frequently and c/r a good amount but my impression was that his range was polarized. He's also playing kinda loose oop so hands like Q6s, K6s, and A6s and offsuit are in his range as well as 67s,56s,86s,and 96s.

I didn't think it made sense to do anything but flat this flop because if i'm not getting it in against trips or a boat im getting it in against a higher FD which dominates me, and it'd be super gay if he rebluff shoves total air but is still winning. My question is on the turn, should i shove or call? If he checks the river im confident i can bluff shove the rievr with over 90% success. Then again, if i shove here he folds all higher Fd's and doesn't get the chance to bluff me off the river sometimes.

i would call vs people who i dont think are bluffing on this type of board way too much. obv if you think they are bluffing here too much then shove

I would play the turn the same way I would play AK.

With AK against unknown I would probably call the turn and bet or shove the river when checked to. Against someone I play regularly I would be much more inclined to raise the turn.

I'd shove and think to see him fold a good amount.

I agree with flop reasoning. I think you see a lot of air here obv.

if i continue id call, his freq would have to be pretty strange for shoving to show a bigger profit than calling
