JJ Hand. Should I raise the turn?

I think your beat on the turn, and only an A can save you, when you will almost certainly be splitting the pot with 4-to-a-straight, which halves your odds at least. A J won't save you either, for the same reason. *

Fold the turn.

* Not the same reason, the reason is in fact that a set will be beaten by a str8, which will certainly be made by a J on the board
