Raise his beatch-ass? And how much?

[DTD]

I think villian was something like 28/12, and I got the impression he wasn't great. Not sure why I felt that as I wasn't concentrating on this table so don't even know how he got his stack. Not much history though, I'm sure of that.

Anyway, assuming he's a break-even player, what to do on the river? We start 200bb deep, so you can raise/fold? And how much?
