Disagree about his range being likely to be super polarised on the flop. Often Qx will be a sizable part of villains range comes to weaker players. This guy
is clearly bad (not a fullstack, playing 5NL, sizing etc) Defo fine with the flop 3 bet here and stacking off b vs b, should have more than enough equity. Assuming we'll be better off c/c down vs air that he likely wont go too mad with is likely an error since we risk losing value vs Qx being oop here when we call flop and check turn.

As played check and evaluate now, if he starts hammering, folding is going to be fine here. I wouldn't excpect Qx to hammer too often now.
