Since he's betting anything on the river, I'd let him hang himself and re-evaluate (and probably call) after he bet. He's not going crazy with a naked Q, and anything better probably raises you on the river anyways. I think the river pretty much ensures he bluffs any two given your read, so why not take advantage of this? I don't like betting here, especially since if he pushes you'll have to fold getting really good odds (unless you can make this call given the read... but then you should still check).
