I noes...
I said the same thing a couple of months ago. But the more you try to explain it the more you whish people would just follow advice, stop loosing money, move up and figure out the answer in the process.

The prolem is that it's a complex situation. First you have to figure out if the button is capable of a steal. If not, then it's an easy fold. - You could make a case for widening your range against a maniac... having played 5NL like a maniac I would advice against that. Most players are prone to opening up too wide and don't understand how to defend, so the best strategy is to just wait for good hands, hit the flop and make profit, and not worry too much about the couple of cents you're potentially loosing by not playing a hand when you could be ahead.

The villains range is divided into value and steal.
How are you going to figure out which one it is?
How far will he go on a bluff? Does he double barrell with air?
When the flop comes A3T... do you c/c him down?

Being out of position here sucks so much more than you probably realize. If you're in position and the initial raiser checks, you can probably take down the pot. From the blinds you have to check and see what he does. If he bets then a steal attempt will be much more expensive. By knowing if he's willing to bet the hand you know a lot more about his range. On later streets you don't see if he slows down when a draw completes, or an overcard hits.

And in the end you're likely overthinking the situation when the opponent isn't thinking at all, and you just managed to trap yourself.
