BB is an unknown.

How is PF?

I feel like the river is likely a split, but there is the possibility of a full house. What's your move on the river?

I'm happy to check down the river. If you feel you might be good or at least splitting on the river, I think a check-call is in order as it lets worse hands bluff.

As played I just fold.

That sucks. I like leading the river more then checking in case he has 1pair/trips but I think you should fold too. In the heat of the moment I'd probably call because I have to see his bluff/donk-trips or at least split the pot, but it's probably a leak.

you should have bet the flop or at least the turn.

ZOMG ignore me I totally did not see that hero has a straight.

Bet 2$ on flop.

I think the river has been played fine, just call his raise. Likely split, but unaware opponent with trip q's could be raising, or against FH/nut flush. Do not 3 bet flop in this spot.
