A couple of interesting hands have generated a diversity of opinions OP.

My 2c:

Hand 1: Villian LIMPED PF AND didn't cap. No evidence of KK. flop c/r is most often associated with 2 pair. Simply put, will you be right about that 2/3's of the time, because if you are wrong 1 bet will cost you 2 unless you are willing to raise/fold. Further, from Villian's POV, the dog hand (K9) would put him ahead if he puts you on AK. I raise the river on hand 1.

Hand 2: Flop raise did give you a free card. H/U I'm OK with it but if you got 3 bet would you fold? On the river, Villian is re-testing after your free card. He has something. Live, I would raise this river as well.
