At river I think either villain has a busted spade draw or straight draw that decides to three barrel or has a top pair like KQ, and of course KJ or 33 he'd play same way.
I think he almost never has a J and could be doing this with a bare K, so I went ahead trying to rep a Jack.
He did shove back and I had to fold.
Should I just fold river outright?
