The AQ hand reminds me of something that was sort of a lightbulb moment for me recently. I think it was M2M who said something in a thread about C-R smaller flush draws (BB vs. BTN) but taking a c/c line with NFD/overs, because we have soooo much equity vs. button's value range and will end up with strong hands on so many runouts.
Everyone is concerned with 3-bet/4-betting ranges OOP, whether to merge or polarize and when, etc., that everyone ignores what their other ranges look like.
