NL25 AQ river decision

[kitaristi0]

Do you raise this river? I was about to, but then I thought, what is he going to call me with here that isn't splitting?

What about the turn play? The two flush worried me a bit, but I think it's more likely he's leading into 4 players on the flop with a weaker ace, rather than a flush draw.
