KK on monotone flop

[Jerk_Store]

Bellagio 15-30, Villain is relatively unknown, he showed down one hand in which he opened from the HJ and had Q9s, other than that he is unknown.

Villain opens from CO, Button cold calls, Hero 3-bets K [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/club.gif[/img] from SB, BB folds, Villain calls, cold-caller calls.

Flop: 8 [img]/images/graemlins/club.gif[/img]5 [img]/images/graemlins/club.gif[/img]3 [img]/images/graemlins/club.gif[/img]

Hero bets, Villain calls, other guy folds.

Hero bets, Villain raises, Hero?

What is my play if I 3-bet and Villain 4-bets? What if Villain calls my 3-bet then raises the river? Any good lines that involve just calling this raise on the turn?
