Lucky or good? (hand feedback please)

I think I played this right but I hate feeling like I got lucky. Would anyone care to comment on this hand?

My reasoning: I raised preflop and he called. He has to expect me to play aggressively when rags flop. Thus if he flopped a monster (which he did), why would he not slowplay? His raise is too large for me to call with most hands. It's large enough that he could be semibluffing (any ace gives him at least a straight draw). Alternatively, he could be betting a vulnerable overpair. In either case, I like the all-in reraise. Am I crazy?
