Hmm.... Normally I'd play this the same way with two people left to call behind you. In this particular case, though, with the two diamonds on the board, I'd probably raise to protect my hand here. You'd kick yourself if SB or BB call down and beat you with a flush on the river.

Turn: Since you didn't raise the flop, MP1 comes out firing again. In cases like this, where I'm HU with someone I'm almost certainly beating and they're being aggressive, I'll play rope-a-dope with them. Let them fire on the flop and turn, and then raise the river. If you raise the turn, as you did, you may or may not get another BB out of them on the river, but if you wait until the river, they'll almost always call your raise to see the showdown, thus gaining one more BB for you.
