Call down with AK?
 

UTG is 80/30 but I haven't had a chance to watch him postflop. I had raised the past 2 hands, 1 went showdown and I won, the other didn't.

I planned on calling a non-diamond river.

he is a maniac. don't fold hands like this to maniacs. he didn't need to ahve a draw to raise like that. he could have any 2 cards he feels like raising this is a very, very, very, very bad fold

Would this play have been acceptable against an unknown?

Against a maniac go with your gut probably, although I pick a better spot than this. Against an unknown this is a definite fold.
