So many options and i don`t like one of those

[recallme]

UTG+1, who is Villain is 40/22/1.2, i took some pots away from him with bluffs, but no big hand between us yet.
Co is 35/20, no History

Hero has Ks9c, eff. stacks 4,1k Nl5k

Uth+1 and Co limps, i make it 280 to go and only Villain calls (uTG+1)

Flop is KhJh5d 685$
V checks, I bet 520, V calls

Turn: Qs
V checks,

Hero is checking, than 1. calling a blnak river
2. folding to a c river

Hero is betting ( how much?) 1. calling raise/shove
2. If called, folding to a donked c ,9/A
3. calling a bet on a blank turn
4. checking river behind/shoving


At first, what line am i taking on turn? What will result on river?
