Betting hard at a good draw on the turn

MP1 plays about 50% of all hands, and calls to the river with nothing. BB just posted.

Kind of curious what the thoughts are on my turn play here. I'd have played it more cautiously if I didn't have MP1 around to sweeten the pot. With both draws, and top pair, I figured I could raise for value.
