Hi RIO, I'm looking for some feedback on this hand. Thoughts on if it's a good bluff or spew?

Side note: Raw hand history doesn't seem to be working with iPoker?

SB posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 1.5 BB) Hero has Qd Kh

fold, fold, fold, Hero raises to 2 BB, fold, BB calls 1 BB

Flop: (4.5 BB, 2 players) As Js 8c
BB checks, Hero bets 1.8 BB, BB calls 1.8 BB

I use a 1/3p cbet sizing with a reasonably wide range here OTF

Turn: (8.1 BB, 2 players) 6d
BB checks, Hero bets 6.45 BB, BB calls 6.45 BB

I use a 80% turn cbet sizining to polarise my range. Barrel seems fine, although now I think checking may be a valid option with our SDV, not sure what is better?

River: (21 BB, 2 players) 9c
BB checks, Hero bets 16.8 BB, BB calls 16.8 BB

We have so much value (most of our SDs get there, so many 2P/sets etc) here that I need to find some bluffs, and I think KQ is a good combo to use. KQo blocks the nuts and doesn't have any spade blockers either and has nearly 0 SDV. In restrospect, I should have potted or overbet river instead.
