Fold w/o more info.
If it's a maniac, we 3-bet, if it's a nit we obviously fold. Sane stats suggest sane raises. If we know the player is positionally aware then we can 3-bet, but otherwise, at 25nl anyway, I think we just get out of the way. We don't know how good we are pre, and the only flop we're happy to see is one with our set in it, and then we're not sure if we can get paid for any more than a c-bet.
