I like the check, i think it is likely that he was drawing so if u bet he folds, if u check he may try to bluff you. However, i think this is player dependent. Against tight players i would just bet the river as tight players more likely have made hands with the action so far, against players who have shown to bluff or float checking the river could result in you winning the game as they bluff shove.

I check the river a lot if i feel villain is on a draw and it works pretty well, even if they check most of the time they weren't calling a bet anyway.

The other possibility is to bet small say 1/4 pot like some others said. This could still result in a bluff raise (altho very rarely) as they view your small bet as weak, plus you get some calls from weaker hands that would fold to bigger bets or check behind if you check.
