1/2 - KKK sees worst turn possible, fold river?

[Burdzthewurd]

1/2 4-handed

Villain and I both have about $270. He's generally straightforward but makes really stupid semi-bluffs sometimes, can't get off TPNK and makes bad peels post-flop in raised pots. His calling range of 3-bets is fairly wide in terms of any suited Ace, any broadways, any pair. I've never seen him double-barrel turn/river with a bluff, and I don't think he's dumb enough to think he's value-betting if he has QJ or JT or something weird. Is this an ok river fold or always calldown?
