I have only 5 hands on MP2 showing that he is a 27/0. He's an unknown.

What's your move here?

What kind of PT numbers would you need to consider taking it to the felt on the turn?

[Jamougha]

The board is connected and very dangerous, I need to know he's a stone cold maniac to go to the felt here.

Fold. Baluga Theorem.

As Jamougha said, only against a maniac am I staying with this hand.
