Would anyone play this hand (KK) differently?

This table was full of fish and people were not folding to PFR. Very fishy table that would hang around with any pair, any pocket pair, etc. No reads on BTN as only played a couple of hands- but did see me show good hand a few minutes earlier. BB is a total calling station who got lucky a few hands back when he caught a second pair on the river and stacked off someone's AAs.


SB ($2.92)
BB ($8.12)
Hero ($5.28)
MP ($2.83)
CO ($7.18)
Button ($3.32)

Preflop: Hero is UTG with K[img]/images/graemlins/diamond.gif[/img], K[img]/images/graemlins/spade.gif[/img].
<font color="#CC3333">Hero raises to $0.12</font>, <font color="#666666">2 folds</font>, Button calls $0.12, <font color="#666666">1 fold</font>, BB calls $0.10.

Usually raise 4BB but went 6 since UTG and no one was respecting the 4BB PFR

Did this dude float an A or did he flop a set? Backdoor flush and straight don't make sense?
