Very nice post and I agree with it in general (hell, I don't think you really said anything anyone can disagree with). But this particular example, I'm not sure how often it happens at NL50 and NL100. In my recollection, very few people would raise here with 77 because they notice that you are very aggressive. In my recollection, they would call if they doubted you had an overpair, not raise. In fact, that is true at NL400 and NL600 too. Very rarely do I see people raising and then showing down hands like 77 here. But I see them calling and showing down 77 all the time when the preflop raiser gives up on his AK. It usually checks down.
