Villain seems competent enough, 24/17/4.0. Seems positonally aware too.

Sure, it looks like the kind of flop where he can stack off with a lot worse - but can he really have it?

Say his calling range for the 3bet is [QQ, JJ, TT, AQs, AQo] then 57% of his range on the flop is straights. If he folds QQ on the flop, or at least only calls one street then shuts down with it, then 72% of his turn continuing range is straights and the rest are the undersets.

Thoughts?
