Raise the flop, I think a re-raise allows you to get away and it might get you to the river free where you can call a value bet for a cheap showdown.

As played, fold the turn. At the 200's , when I come across guys betting like this it seems to be they have a solid (set or 3rd nut straight), but not great hand and don't know how to play it, but they know enough to know they should be betting. So they bet goofy amounts which have no rhyme or reason to a thinking player.

If this guy was bluffing three barrels, then you have just found an undiscovered ATM.
