Villain is a reg, no reads. OTF, I would assume he is only raising sets, small and mid PP for protection, some of his FD and maybe 8x, so we have an easy call. I would also assume he keeps betting all his sets and 87s almost 100% on that turn, so I decided to bet again to get value from his FD, 99, TT and random 8x.
I think I completely butchered the river: against that hands that I am putting him on, I should probably bet more like 1/3 pot. As played, I could not think of a single hand that would shove river after checking turn, so I called.
Exploitatively, can we get away with folding this river? Although the way he played the hand makes no sense, I do think 90% of regs would not shove that river as a bluff with that SPR, plus it is still possible that some % of the time he still has sets in his range.
