Welcome back!

Hand 1: I don't like that he 5-bet pushed here, but you have to call. Nice flop! (Unless he had KK...)
Hand 2,3: Standard against opponent.
Hand 4: Villians range include lots of flush draws also, so Check/calling the river is optimal IMO. NH.
Hand 5: Yea, flop is a fold. Turn is a "UGH, why didn't he bet more", but I still probably fold with UTG still to act (Check/Raise coming!!!). River is not as bad as the other streets though...
