Two Pair facing Raise from a Maniac

[rwdvc]

Small sample but the villain has a VPIP of 75 and PFR of 16.5 with 3.5 AF

I raised the flop to try and define his hand, so after the flop I'm putting him on Ax. I'm thinking the turn bet is okay but in retrospect I'm not sure I like it that much.

If you are going to raise flop, raise it more. Also raise turn more for value. Call river. Hand looks pretty standard against a maniac which I'm assuming he is if these stats are over a reasonable sample.

Who value bets this river? I'd probably just call but I'm not so sure this is appropriate given the villan...
