I understand to put villian on ranges but mid pocket pairs are almost always going to be included in that range, but AJ or QJ is also going to be in that range. These were not specific hands and maybe I use the wrong example substitute a 6 for the 8 and villians holding pocket 6s.

By flop raise and turn raise what I mean is I am value raising the flop turn and river and then villian pushes all in on river. There are no straights or flushes possible. I have top two pair vs. and under set. How do you ever see this before the river push.
