Tilt 1k, Turn pair into bluff?

[Bond18]

Villain is kind of between TAG and LAG, had been doing some stupid [censored] like opening 4X in LP and what not.

On the flop the only hand i can see him check calling that contains a jack is JJ, as i'm pretty sure AJdd would check shove a lot.

On river villain thought for a little bit, before firing out a bet that's either leaving room to fold or a value?

Thoughts on this?

Does shoving&gt;calling here? If he's turning any other hand into a bluff here i don't think we can beat it given texture, and if he's thin value betting like a checked set or something calling is going to be a spew.
