One of the first hands I was involved with villain. The raise is pretty small but on the other hand is there a hand he would raise with here that I beat? I have 2 pair, but there are 3 to a straight on the board, and even just a higher 2 pair is quite possible. AK/JJ+ can probably be ruled out - TT, QJ, QT or 89 are all quite possible. Would he raise AQ here?
My thinking here is just that the board was so coordinated it doesn't make sense to raise as a bluff. Also if I flat I am OOP for the rest of the hand and in no better a spot if he barrels the turn. Is folding here correct? Or a little too weak?

I don't really like how I played this because I think my river betsizing almost invites a raise. I would usually have bet a little bigger but I felt after he called the turn that he might have an underpair type hand that I could go for thin value from. When he raises I really have no idea what he's representing. I didn't want to level myself into thinking he must be bluffing since he couldn't possibly have 2 strong hands in a row but on the other hand I don't know what made holding flats the turn and raises the river.
Again, much like the last hand, I felt this was a spot where he reps a very narrow range but it doesn't make any sense for him to be bluffing either because the 3 is pretty much a total blank. And all I have is a bluffcatcher.
Thoughts on both hands appreciated.
