Hand 1 - some reads on villian perhaps, slowdown on the turn raise
Hand 2 - what kind of player is UTG, could he be c/r you with JJ-KK on the turn? Is he raising these hands preflop?
Hand 3 - What is your read on UTG, What hands are you putting UTG on? Looks like a easy fold especially by the river

Not to sound like an [censored], but I think you need to start watching what kind of hands your opponents are showing down. Reads will save you a lot of bets on hands like the ones you posted.

*edit hand 2 - I have no clue what I was looking at above, but on hand 2, I would check behind on that turn and call a river bet from villian
