Table is very tight with the exception of the player directly to my right. He's raising and calling and re-raising and pushing like nut and I'm letting him basically run me over so far.

He's at 53/37/30 after 49 hands. In 10 hands in CO/OTB (LP) he's 70/60/30. So he's basically a maniac. If he hits any part of the board he'll call down and he has been hitting.

I'm now SB and blinds are 25/50 with [9c] and 3480
CO 3465 opens for 150.
Button maniac calls 7375 behind.
I re-raise to 650.
CO folds.
Maniac immediately pushes all-in.
There's 4330 in the pot and I need to call 2830. What range do I put a maniac on? Can I call?
