Folded to me in LP with a maniac in the blind

[SlantNGo]

How should I adjust my open-raising range and my postflop play when it's folded to me in LP and there is a maniac in the blinds? Let's assume that there is a 80% chance I will be 3-bet (feel free to talk about how your strategy changes if we drop this to 40%). Coming from a full ring background, I didn't run into this situation much, but with a maniac behind me (to my left and not in the blinds), I tightened up a lot on my open-raises, especially on the K- and Q-high offsuits, while not so much on the Ace high ones, because I perceived them to have more showdown value (I would C/C them down unimproved if the board texture was favorable, i.e. paired).

Anyways, the particular villain in the next two hands was 80/50/4, and I've never seen him fold on any street after a pre-flop raise:

I think I should be check/folding the river here, correct? Maybe even the turn?

I think I should just fold this pre-flop knowing that SB will 3-bet me 90% of the time. However, given that I got myself into this jam, what should I be doing on the flop? I think I can peel then check/fold the turn unimproved. Calling this down was just terrible IMO, even with the double-paired river.
