Missed flop c/ semibluff and now wann shoot the second barrel

[recallme]

Game is 5 handed effective stacks 100BB.
I stacked Villain ( 20/16/3) in a 3bet pot where he bluffed his Q´s on turn into my set of Aces, 5 obits ago.

Hero has QcJc

UTG folds, Villain makes it 40, Co calls, Sb folds and Hero squeezes to 180

Flop is Ts9s3s 420$

I am considering betting, but how do i respond to a shove?
I checked planning to shove AI.

Villain checks
Turn is 5h
Hero bets 280, Villain calls

River: 3h 970

Villain has 550 behind.

Is this a shove?
