I think a flop Check-Raise could work. It would protect your hand better than betting. MP1 is an aggressive player and I think there is a good chance he will bet if checked to. Did you have any continuation stats on him?

I am also making a crying call on the river. For tow bets, I am giving it up. For one, I am not. I do not think there is any danger of MP1 trapping since he would have raised after your bet on the river.
