Mid PP vs. habitual floater

[jc1418]

.5/1

villain floats alot of freakin flops
I have been ultra aggressive pre and postflop for about an hour

Villain (UTG) 120
Hero (BB) 170

Hero dealt 8c8s

villain limps, all folds to me in BB, Hero raises to 5, villain calls

flop Ks 6s 2h
pot 10.5
hero ???

I am misplaying habitual floaters for sure, do I lead and give up, bet two streets and check? This guy will bet air on the river if checked to. Should I just check/fold the flop here? Also when I hit top pair or overpair on a low board vs habitual floater I usually go for 3 streets of value. Bet flop and turn crai is more optimal line right?
