It's better to check or bet this turn?

[Raist0000]

6-handed game

I open raise in UTG+1 with KQo. Only the big blind calls me.

Flop: Qd As 5d
He checks, I bet, he calls.

Turn: 7h
He checks, I ???

The only good draw he can have is a flush draw. But his most probable holding is a weak ace, and is planning to call all the way. Perhaps he have a worse queen.

Villain is 31.4%,19.3%,1.7,36.5% (VPIP,PFR,AF,WTSD)
His Flop-turn%=65.3% and Turn-river%=71.4%
All of this in 1633 hands. No more reads.

Two last things:
1) If I had a different opponent, would your answer be different?
2) Would your answer be different if there was no flush draw on board?

Is this villain able to bluff/ semibluff this Turn? then i would be more inclined to check behind. I would prefer the bet Turn check River is villain woudl nor c/r bluff semibluff this Turn but most villains are.Kind of depend son your image and on your history too wich line too choose, i think both are fine...what Rivers are we folding btw if we check and he bets... a diomond? a 5 ? nothing?
