How the heck do you play overpairs out of position?

[xcrack999]

Villain has been very loose-passive. He probably saw about 90% of the flops in the last 30 minutes or so. I'm very confused about how to play this hand correctly, so any help is greatly appreciated.

against loose passive, the way you played it is fine.

against loose aggressive, I check the turn.

That's fine.
