[Wolffink]

I'd fold here.

This seems to be the textbook case of possibly putting in a lot more money, only to get, at best, half of it back. And there's a significant chance you'll be quartered--or counterfeited. Fold and get on to the next hand.

What will you do if he raises the pot on the river? You're in the same sucky situation as in the turn.

And with only the nut low, out of position, I think you should either check the turn or bet less than the pot. Put yourself in your opponent's shoes--what would you like to see your opponent do? Also if you do call in these situations, you're setup to get quartered and/or counterfeited on later hands.

Folding cannot be wrong here. You have no chance to scoop.

Possibly you might be able to bluff the pot on the river. That might be a reason for calling, but I dont think it switches a fold to a call.
