Lucky flop. I guess I could have raised his flush on the turn, but what would be my best move to increase EV on flop & turn?

PokerStars No-Limit Hold'em Tourney, Big Blind is t20 (8 handed)

Final Pot: t1150

Results below:

Without the Ah, he probably would have folded if you'd bet the flop. But betting a little something on the turn may have extracted more chips out of him. Basically the river betting, one street earlier, and then you could do it again on the river.
