What are you doing preflop with this hand? I don't think it's a good call because at these stakes, it will most likely end up 3way+ very often and I don't think my hand plays very well in that spot. I therefore decided to put it into my 3betting range because it looks like a decent enough hand. However, I find that people still often overcall hands from the blinds they should just be folding, so I won't get the pot HU as often as I want.
Can I just fold this pre at these stakes?

Flop: ($3.70) 3 2 8 (3 players)
SB checks, CO checks, Hero bets $2.76, SB calls $2.76, CO folds

Turn: ($9.22) 2 (2 players)
SB checks, Hero checks

River: ($9.22) Q (2 players)
SB checks, Hero ?

I think post isn't super interesting. I decided to cbet the flop because it's a great board for my range and I block TP, decided to giveup on the turn because I figured he has an overpair a lot of the time and likely isn't going to fold no matter what. You could think about turning this into a bluff on the river but it's probably still unnecessary at these stakes. I don't have any diamond blockers and he's probably still finding a call a lot with PPs or if he somehow backed into a Q.
