I think i prefer bet/fold than check/call, especially as it gives them a chance to bet this much!
Imo it's not worth it, $15.30 to win $29.5, means he more than bet the pot and at this limit they love their draws so he could easily be chasing.

If it was the T that came on the river i'd be more inclined, since it was the OESD that hit and not a gutshot... so fold.
