QTo vs maniac. Am I chicken?

[Donkey Kong]

Villain is a full blown maniac 75/50/2.5 over 100 hands. Goes way too far all the time. The other guy is a standard fish (47/5/1).

Should I keep jamming the turn or slow down? The flop call-3bet from the maniac made me think at least he had some sort of hand.
