I think this demonstrates just how bad most are at playing post flop. "Post flop play" by definition is NOT just about aggression to take a hand. Too many times if your running into thin spots with premium hands it's just as the commentator of the hand described as 'putting good money in bad'. Premium hands hold most strength as described by a pair or over pair. When the board texture becomes apparent for a hand by opponent that is ranked by 3 or more cards the premium hands go down in strength. Johnny Chan has great reads on when to push it through somebodies heart or to give it up cheap. Many of which can be found on youtube.
