Thanks for the odds,Fnord
I will keep them in mind when I gaze at my low pair.
In early position I would probably raise. But in late position I call or even fold (depending on te situation on the table).
Maybe it´s all up to what you are willing to pay to see the flop.
So if I simplify you calculation. It pays 1 to 8.2 to see the flop.
After that there are to much factors.
