Nice post muzz. I'll wait before answering, let some others take a crack at it. I'll just add this comment, about WHY the first two questions are great for folks to think about.

Preflop, we estimate the probability of Villain holding AA and QQ as EQUAL.

Postflop, however, we correct our estimates. Villain is TWICE AS LIKELY to be holding QQ (pair + gutshot) than a set of Aces.

The mathematical term is "conditional probability," reworking the estimates of probabilities based on additional information or conditions. And tons of good poker players have trouble with it. Heck, most of us get surprised sometimes with how the flop can change the ranges and equity.

Interesting post. Thx muzz.
