Help! Called a raise and flopped bottom 2!

[J Chap]

Villain seemed relatively quiet so far, so I gave him credit for a good hand.

Should I go harder on the flop or the turn? How'd you guys like that 0.50 blocker bet on the river? I really feel like it's very unlikely I'm ahead, so I didn't want to put any money in.

Better line requested.

How'd you guys like
