I don't know how to play big overpairs

Any help here? This has been a leak for me for quite a while. I play party 50NL, and I cant find a consistent pattern. Here are 3 examples from yesterday. I just dont know how to tell when to let them go. I normally try to look for a ~half-stack showdown but it doesnt work out a lot of the time.

Hand 1. Bad guy is 60/17. I normally reraise a bit more than I did here, but I'm not sure if that would make a difference in this case. I guess I should reraise the flop big. Against a bigger stack I could let it go at that point, but against this guy I think I'm probably AI no matter what so I call and let him lead. If he lets me showdown cheap then I will. Or should I push that flop hard? I essentially gave him a cheap draw.

Hand 2. I dont have a ton of hands on bad guy(34). He's 50/17 at this point. He was playing decently for being that loose...but that's not many hands.

I think the critical hand is hand 1, why did you flat call the flop? With the straight draw and the flush draw out there you need to re raise villain, you need to remove his odds make him pay for his draw. I think hand one you should re raise him $15-20 more.

The third hand is fine.

In the first hand you need to raise somewhere postflop. Given stack sizes I wouldnt mind a raise on the flop and then pushi9ng the turn when checked to. As played on the flop I push the turn.

In the 2nd hand I really dont like putting in such a small 3bet if we are just going to fold to a raise. I wouldnt mind a call of the minraise and then a c/r AI on the turn or just betting the turn and pushing the river [or calling a turn push]

Hand 1: I re-raise the flop AI, it's $22 and he has $20 behind and I have an overpair.

Hand 2: Flat call the flop, c/r AI on the turn. Fairly dry board, so c/c works too.

Hand 3: Easy.

ok not even looking at those hands, are you all willing to end up AI with AA or KK overpairs against non-scary boards? How often do you win vs losing to 2pair/sets?

...

as previously said,
the flat call on hand1 is terrible. Must raise for info here.

rest looks pretty standard.
Hand 2 screams set
Hand 3 I am getting it in on the flop with a player that aggro.
