guess I can exclude him having a set and playing like that instead of
x/r?

I think people sometimes donk strong part of their range too. He can have all type of hands: sets, straights, pairs, overpairs, FD and overcards. So flop raise with bdfd is fine, can expect to see re-raise sometimes...
Turn I'm considering calling, we don't have direct odds but if we win sometimes when hit or when bluff it is seems slightly profitable.

I think 33/19 with this board he almost hit this type of board most of the time, i would go for call instead of raising, because his bet size is just less than half pot ill take the line of calling because of his bet sizing giving me a very good price.

From what I've seen, many people donk half pot or so with their draws, sometimes with marginal made hands if they're fishy and hate check/calling. Can't really read much into it. Raising the flop is fine and calling is fine as well.

Turn is rather poor (though he shouldn't have a 3 too often in the SB). I would probably fold here since there's no backdoor draw anymore, and not all of my outs are clean (the hearts could make the villain a flush). You can have plenty of better hands here -- no need to continue with this hand.

Raise Turn, bet river

Fair raise OTF, but I'd go for a slighty bigger size.
On turn, no way you can fold vs this small bet with OESD.
Call and evaluate the river.
