Ha, you and I have different definitions of card dead if we've picked up a couple of pots / up $100 in just 45 minutes (I call that "sunrunning").
I'm also calling to setmine preflop.
Even though this is a raised pot, the SPR is still on the medium high end. I would obviously stack off against the maniac, but stacking off against someone else might be a little dicey (especially against passive players who don't go nutso with pair + draw).
I would raise the flop. I want to isolate the maniac and play a big pot against him, especially before a bunch of scare cards come. I would probably make it $85 (a maniac is *never* folding any draw on the flop), which will create a $195 pot for a $160 shove on the turn.
Honestly, a difficult spot now. I feel easily committed against the maniac, but I'm not as thrilled to be committed against the other guy. Still, I'm assuming there are enough small overpairs (TT/99/etc.) and two pair plus maybe pair + draw that decide to go nuts that I would just ship it in. Plus we've only been playing with the other guy for 45 minutes, which is simply not nearly enough time to get a nit read (which is what we'd probably need to fold here).
