Fold. He's not likely to have picked up a diamond fd and he's more likely to raise the flop rather than the turn with a spade fd. This is a 9 or 33/22 too often to continue.

Edit: And yeah, I also like the turn bet for the same reason K stated. Also we're pretty likely to get called by a lower PP on this board while many rivers will kill our action.
