River spot, bluff or give up? HU .5/1

[sc000t]

Think I can post this from memory, if not I'll go dig up the hand.

HU stars 100max PLO

Hero: $115
Villian: Covers

Villian is a little "odd". Plays a weak passive game mixed in with some random raises from the little hands we've played. Limps alot from button but has 3bet me 3times in like 100 hands OOP. One 3bet got to showdown with a A345ds for villian.

Hero is on button with A [img]/images/graemlins/diamond.gif[/img]T [img]/images/graemlins/diamond.gif[/img]6[img]/images/graemlins/spade.gif[/img]5 [img]/images/graemlins/spade.gif[/img] and raises $3
Villian reraises to $4 more to $7 (I know, weird)
Hero Calls $4

Flop: 9 [img]/images/graemlins/diamond.gif[/img]2 [img]/images/graemlins/diamond.gif[/img] 7[img]/images/graemlins/spade.gif[/img] ($14)

Villain bets $10
Hero calls

Turn: 6 [img]/images/graemlins/club.gif[/img] ($34)
Villian bets $25
Hero Calls (anyone raise?)

River: K [img]/images/graemlins/heart.gif[/img] ($84)
Villian checks
Hero ??? (has $73 left)



I was semi worried my hand would look exactly like it is...a missed draw. What do we do here? Give up? Bet? Raise or fold the turn?
