Live 5-10 River Decision

[BartHanson]

Hero is in the small blind with $1500. Villain is under the gun and has me covered. Table is fairly passive not much preflop raising. Villain is a non tricky fairly loose passive prop--Mr. Kim for those of you that know me.

Villian limps under the gun. Folded around to hero in the SB with Qd Qh. Hero makes it $40 to go. Villain calls.

Flop: As Kd Qs

Hero bets $75. Villain calls.

Turn: 8d

Hero bets $225. Villain thinks for a moment and calls. Pot size~$680

River 2d

I have about $1100 left in my stack. Plan for river here?
