Interesting hand against my new arch nemesis

[TheWorstPlayer]

Main villain is dariominieri or whatever. I'm sure he's a lot of people's arch nemesis bec he plays like 35/30 or something preflop which gets him into tangles with everybody.

But we've been going at it pretty hard today for like an hour or two and have played several big pots. I stacked him when I reraised KQ and called his push on a river K to beat his flopped mid pair. Then he stacked me when he flopped trips after calling a reraise with 67s against my overpair. Then I stacked him when I flopped a straight against his set. So now we're onto this hand.

I was definitely going to push a blank river. I don't know what I would have done if he had pushed a blank river. I was probably folding if he pushed a scary river. What do I do on THIS river? I don't want to value stack myself, but I also don't want to leave a lot of value on the table. So do I bet or not?

(P.S. I know everyone bets the flop every time. I don't. Get over it.)
