Unknown villain.

I tend to CB 0.33psb my entire range at this flop.
But, villain is oop, we block lots of top pair and the NFD.
That's why I checked it back.

Turn I don't know if I'm raising or just calling. Of course we may find lots of value but I prefered to keep his bluffing range.
Maybe we should raise here and get value from two pairs, sets.

River he makes a small bet and I decided to raise small, maybe it's a mistake.
Should've we raise it bigger? I think he calls two pairs and sets when we do make a bigger size and we might find a fold when he clicks it back (possible 76s, A2s, 22?).

From the theorically view, solvers might go for 3barrell shoving the river, but in a real microstake scenario I don't think we'll get more value doing so.
