AcQc checkraised on KcKd6c flop (20/40 live)

[betgo]

Live 20/40 holdem. I am not familiar to table and they don't know how I play.

Loose player limps UTG, I raise in 4th position with AQs, button calls, BB calls. Flop comes KK6 giving me a flush draw. Checked to me and I bet. BB checkraises.

Should I just call and call him down if I don't make a flush? Or should I 3-bet? If so, how do I follow up if the turn is a brick? Should I just jam this or call it down.
