Any better lines on flop?

[abscr]

No read on opp. I had been playing a pretty solid LAG game recently. I wouldn't expect my opp. to do this with a draw. I was pretty confident at the time; anyone think I should play it differently? My only huge dread would be a set/two-pair with the flush draw, right?
