$2NL KJs OESD+FD vs Maniac

[TNreg]

Villain is 47/19 over 73 hands at this point. Very aggro postflop (67 AFq). Hindsight tells me I shoulda just left the table with this dude on my left. CO is 54/0 fish. If I cbet this flop I expect to get raised with all sorts of rubbish by the BTN so the plan is to check/call... let him bet for me. Good/bad? What's the best line on the turn here?
