Do I in fact have an easy turn fold?

[DMBFan23]

I feel like the better players are folding this turn, or possibly the river UI, while chumps like me are calling it down. SB here is a 34/17/3, I've played with him a whole lot and sat down because he was playing. main villain is totally unknown, what do y'all do here?

If you do fold, how much does the fact that the flop was OESD'd impact your decision? if the flop were gutshot'd, would that make it a turn call for you?

he definitely played it like a str8 draw. after you showed a lot of strength and he's sayin he can beat you, i'd fold the turn.
