Limp caller check min raises on a paired board

Villain is new to the table (why is this always the case?!) so no reads.

I'll explain my line. When getting check min raised, I thought I was WA/WB and would gain little from a reraise. I was way ahead of any underpair, which may have decided this was a good flop to take the pot away from the preflop raisor. I was way behind any J.

So I called hoping to induce an underpair to keep playing at me. Same applies on the turn.

He checks on the river, so given how weakly I've played it I'm putting him on an underpair (or complete air), and figure there's some value to be obtained. Should I bet for value here, how often do I run into a J/full house?

Comments on my whole line would be appreciated too.

I like your reasoning and line. Some unknowns wil check a J/boat on river but I think it is way more likely it isn't a J/boat by river check.

I think 1/2 PSB is good for value on river.

On the river, the villain has ~$5 left, and with his check, I'm definetly interested in trying to get as much of that $5.05 into the pot as possible. I probably bet ~1/2 pot and hope he shoves non jack...

I too like your flop/turn play. My initial instinct was to reraise turn, but I agree that you're likely wa/wb
