I think you have to bet more on the flop here. 1/3 pot doesn't fold much, and doesn't tell you much about your opponents holdings.

I like the turn bet a lot more, and would call on the river. I have trouble giving villain credit for the straight, lower set perhaps.

If the straight beat you here (46 I guess - flopped OESD)I think you might have been able to get rid of it with a decent flop bet, but he doesnt drop it to the 3/4 pot bet on the turn, so maybe he was destined to outdraw you.

I don't think you should fold here though.
