Zoom hand:

Reasonable sample on villain, and he seems quite nitty - 20/15/6.7, have seem him be 3bet four times and he folded two of them. Plays fit or fold postflop, having folded to 60% of cbets.

I don't think he can have too many queens to call the 3bet OOP here, so I'd be cbetting this flop with my entire range.

Am I wrong?

Hero???

Ps. I'm not sure I like pre although I did have a nit behind me and a fish in the blinds, but I can think on that on my own - I'm more interested in this flop texture after this action, regardless of my cards.
