I feel that I overplayed the flop and I think the call down might have been pretty standard.

Any opinions on the matter?

The call-down is fine, maybe calling down after the c/r is a possibility since he could be bluffing on this ragged board and you don't want to fold that. Since I don't think he's capping a worse J you only lose 1 sb when that's the case and you neglect to 3-bet.

FWIW, I never trust people buying in for the lowest amount permited. How does other people view this?

Last thing, he bought in for 10$ - 5 BBs right?

Oops, my bad. Yeah, bought in for $10.

Seems like a good spot to call flop and turn and raise the river. You maximize value against bluffs and with his stack size he can't 3-bet the river if he's ahead.

This might actually be the best line against an opponnent with a full stack, at least if you think he's sane enough, that you can raise/fold the river.

Being really worried about being behind, when he raises the flop is weak/tight thinking. Sure it's possible, but in reality not that likely (meaning it's a lot more likely you're still ahead). There's a lot of weaker jacks, pocketpairs, acehigh hands and pure bluffs, and people often wait for the turn with trips.

I haven't gotten back to this in a bit, but villain has 53o for fives full boat.

I didn't like the flop cap. I figured he'd call a 3-bet with any top pair hand, some pocket pairs and ace high. I figured I was at best splitting the pot when he capped.

that only shows that he had garbage and would have gotten it in with some pp also
