PLO Beginner, KKxx flops superdry undercard board

[MikeyPatriot]

I watched a couple of the cardrunners PLO/HA videos and got an itch to finally sit down and play this game for real. I've been running extremely well this session when this hand comes up:

Villain (SB) $70.45
BB $38.05
UTG $24.65
MP $72.40
Hero (CO) $135.35
BTN $49.25

Hero is dealt K[img]/images/graemlins/spade.gif[/img] K[img]/images/graemlins/heart.gif[/img] 8[img]/images/graemlins/heart.gif[/img] 3[img]/images/graemlins/heart.gif[/img]

UTG calls $.50, fold, Hero raises $1.75 to $2.25, BTN folds, SB calls $2, BB folds, UTG calls $1.75

Flop ($7.25)

SB bets $4, UTG folds, Hero calls $4

Turn ($15.25)

River ($29.25)

SB bets $16, Hero...

FWIW, if villain is paying any attention, I should be viewed as playing loose and aggro, but not showing down crap. Off hand, the only hand I remember showing down is a set that filled up on the river that stacked some awful calling station.

I think my turn call is bad (I think it's bad, period) here if I'm not calling river, but I have I think this guy has a set (full on the river). Should I just be folding this turn given his action? Or is this a standard call down?
