at the low stakes (lower than what you play 6s 11s) mostly what has seemed to work for me is raise a little less in position as they will call with random trash you don't have much fold equity with your 85s and it doesn't play amazing postflop you can work in some limps of your own without much trouble
oop you can just check your often better off folding even with above average hands (ie. A10 QJ they have position and you are beat more foten than not by their range so you can avoid difficult spots) to most of thier preflop raises if they are doing it rarely only raiseing premium cards (getting called more often than you would think) as raiseing with marginal hands just becuase they are ahead of their range is not a the best play because you increase variance haveing little to determine if they might be ahead or not +being at positional disadvantage while they are easily outplayed postflop anyway you can just keep the oop pots small and in position pots larger that alone is very good
reduce your c bet frequency slightly and keep betting for value always you can bet bigger against many (2/3, pot size, or overbet) of them as they might have no to only little understanding of pot odds and hand strength you can in some situations shove for value there is some spots that they should never ever call you and will flip up god knows what
2nd pair can often be good enough to get a bet and then check down 
it can be extremely fustrating to run card dead against loose passives but you have a good edge on them and if you think about many of their tendancies to exploit you can often crush them
the fact they are usually not thinking into the game your ranges or tendancies gives you a big advantage (ie. bet every paired board with huge fold equity and some of them will never play back at you)
FOLD
^^^ thats important if its a marginal situation you can keep the pot small and fold when they bet or show strength your much better off letting them bluff you a few times than getting it in bad unless they are constantly getting out of line and giving you good reason to keep them honest
play straight forward don't try tricky stuff it may work sometimes but you are better off in the long run not trying you have a good edge without getting in difficult spots
new myself so you can pick and choose what you want to take from this and with a grain of salt

The easiest way to start playing them is to just check your BB alot.  They're losing equity by letting you see flops so as long as you're not spewing hard post flop, you won't be giving up much of an edge.  They'll play all the big pots OOP and if they're bad, your SB play will more than make up the difference.  Eventually you can learn how to merge or polarize your OOP raising range depending on if they limp/call often or mostly limp/fold.
Against cog dissonance, for example, I would just check beck about 85% of hands, raise my top 10% maybe a little less, and then raise a few assorted hands based on a randomization process (or really, you could just dedicate yourself to raising like, 34s-89s and be fine).  If you always checked back against cog dissonance, he'd have a hard time making money so long as you raise close to 100% of buttons.
Keep in mind, he's a nasty player, and not only do 99% of villains fail to make this kind of adjustment against his game, but even if they did, he could just as easily switch it up and take another approach.
Heck, look at my PF range.  If you 3bet ATC you'll take a nice chunk of equity from me in the early game until I've played you before or adjusted.
