The Sb was a bit of a maniac. About half an hour before this hand he pushed all in on a 2-diamond board with 83 diamonds and it hit. Pre-flop is standard, or could I have raised more?

Not raising flop is bad I guess but I was cartain he would call or raise any bet. But I'm making excuses I suppose..

Call river?
