A weird hand with a maniac

[TheWorstPlayer]

I basically have played no poker all month. But I decided to play a bit tonight and ended up on some weird tables and in some weird spots. I'll try to post a few interesting hands from tonight. Here's one (I think).

BB is literally playing at 71/41. He had a 3k stack when I sat down and now he's in the process of donking it off. CO is PoorUser. I figured A8h is too good a hand to fold at this table where everyone is deep and there is a maniac just waiting to give me money. But if I raise, the maniac will probably squeeze and then it's just going to be ugly. So I limp planning to LRR the maniac, basically. Unless a call looks better in the moment. But then PoorUser raises, and the maniac just calls. So I decide to LRR anyways since PoorUser can obviously just be isolating my limp and he'll respect a LRR especially with the maniac acting behind him. OK, plan goes well. Until maniac calls. Now what?
