Pot flop, fold to a raise, unless read dictates otherwise.

For the raise preflop, It is definitley a play I will try to pull. There is $2 in the pot, and I might pop this up to $3.

If you were to lose everytime you were called, you would need to win this > 60% of the time for it to be +EV. They should fold it > 60%, but you of couce have +EV postflop if you get called, and can make a standard c-bet to take down the pot. It depends on the table, though, and in a lot of loose $50 games, this is not a good play.
