Worst card with overpair versus nut case

[notreallymyname]

I am having a [censored] month and have decided that I've clearly forgotten how to play during a forced break last month, so I need SSNL's help. But enough of the psych board content.

Mainly I want to know what you think of the river call here, but comments on the play of the entire hand would be welcome.

Main read on the villain is "absolutely terrible, aggressive and possibly almost completely unaware of his hand strength", he 3-bet then 5-bet all-in (small raises) his 40bb stack with AJo against an early raiser (me, with KK and doubling him up when he flopped an A). That play was the main reason for calling the last $30 getting about 3.5:1.

you're four betting to get stacks in yes? so why minreraise?

4b to $25 and the hand plays so easily

4bet to ~$26 and push any flop against this guy. --&gt; Problem solved.
