Villain were quite agressive with over 12% raise flop after 1k hands, high 3 bet high agression etc. I think my hand work nice as a cbet and check back. When he raised me wasn't sure if have to defend this hand but villain representing only sets and i have 2 backdoors 9 is out most of the time vs this opponent.

On the turn he prob doesn't have set becouse wouldn't he want go for stack vs my overpairs? Raising turn?

On the river he shouldn't have many Ax and i was thinking that he from flop representing nothing especially with this small size on the turn so I thought he has nothing most of the time and trying small bet to fold whatever when he doesn't have showdown value. When i can have all 2 pairs especially on Ax so wanted to wanted to check if hes bluffing with the lowest prize so i min raise river. Hard to put me on the bluff, i was concidering shoving but if i want to fold hand worser than 1 pair hand why would i risk so much if he will fold to min raise if he has nothing?
