An odd river decision

[Aaron W.]

Villain pretty loose passive preflop. Postflop, he's been a mixed bag. I've seen him overplay a couple weak hands and underplay a strong hand. In other words, I haven't made sense of his postflop play at all.

Do you 3-bet the turn raise on something that resembles the classic slowplayed monster?

What about the river? I don't want him to check behind (if his seven just got counterfeited), but I don't think bet-calling is very intelligent (what is he raising on the river that I beat?).
