I probably should have raised pf or bet more on the flop. I can see every villain on flop calling with a draw but by the river, villain's bet seems more like blocking or a last ditch stab than hitting. Thoughts.

raise pre, bet more on the flop. A PSB on the river is imo really bad. getting 3 bet here would really suck and no hand in villains range is puting a blocker out there and calling a pot sized raise
