If you're assuming villain is competent, your pot size bet on the flop narrows his calling range. I think there are plenty of AQ10x and Q109x in his SB raising range and his competence adds more of these hands in his turn check-raising range, you also block Kxxx with KK. I don't think you need protection from much; heart draws don't make up that large a portion of his range, I don't think he has a lot of bare Q10xx without a 9. Betting large so you don't get bluffed out is not a thing; your range also has plenty of Q9xx and AQxx. You are certainly repping AQxx or QQxx if you pot turn, although this isn't relevant. Without further reads I would check back, against opponents who have a significant leading range I would half pot turn and fold to a repot.
