Been bothering me all day now. Another vs. a maniac (50 FR)

[MTPaid]

Opponent is 50/13/33 over 40 hands but up 2 stacks. He's won last 4 hands he's been involved in consecutively (all raised preflop) as well. Here are his results:
Hand 1: PFR 88, flopped top set, picked up a stack
Hand 2: PFR 22, flopped bottom set, no action on flop, showed set
Hand 3: Called PFR, called c-bet on [9c][9s] flop, pot bet turn blank, raiser folded, showed [4c] for the bluff.
Hand 4: Called PFR, c-bet, turn pot bet, checked river with [5s] on [7s][9c]........... board. Opponent only had a set of 7's.

So he's not folding and he's getting slapped with the deck.

Hand 5: 7 handed I'm SB [Qs] with $45.65
50/13 is UTG+1 and raises to $1.75, Button calls, I call
[4s][5s]Pot $5.75
I check, UTG+1 bets pot, Button folds, I c/r all-in for $43.70 total.

Now that I think better of it, am I right that against this type of player I probably only have fold-equity against hands that I crush? But then again, there are only a couple of hands that I don't want to see here: Set obviously and AK with . Everything else, I've got at least 12-14 outs against.

So should I only be c/r'ing all-in here if I want him to and think he will call? Or from what I've seen in the previous hands, should I think he'll call with something like KJ minus, QQ minus as well?

Sorry, forgot to add the cards from his 3rd hand. Fixed.

I've been thinking more along those lines now BK.
