200NL TPGK vs maniac

Villain is 56.4VPIP/47.4PFR over 75 hands, with a 31%WTSD and postflop aggression frequencies of 61/83/33. He pushed me out of several pots early in the session, pushing a full stack into a 20$ pot on several occasions. He once minraised my flop PSB cbet with bottom pair and a gutshot, proceeding to call a full stacked third player all in after I folded.

I probably should have limp-called him preflop. Other than that, is there anything that should be done differently here? Anyone lay this down somewhere?
