Standard hand against people w/o a brain?

[PokerJans]

Wild and aggressive 6 handed must move game

Crazy pregnant Korean (CPK) lady who seems as though she is about to bare a child with in the next couple minutes limps UTG. She has been raising almost every hand in an attempt to play with the guy on her right.

Seemingly passive dude limps next. I limp K8s. Young kid who thinks he has brain raises on the button. SB folds and BB with is a total nut case fish calls.

J85dd

BB checks, CPK checks, SPA checks, I check, and for whatever reason the button checks.

J85 5 ddhh (two flush draws now)

BB checks, CPK now bets, SPA calls, I raise, button hems and haws and folds and they both call.

River is some blank

Check, check, and I bet for value?
