I consider this bad luck more than a bad beat. He played it reasonably at each opportunity, and when the (majority of) money went in he was way ahead.

I'm too lazy to do the pot-size math, but when he check-raises you all-in on the turn, I think you need to start seriously considering that you're beat, since it would appear that you're pot committed at that point. If you are committed and he realizes that you basically have to call, I think the only hands you're going to see that you beat are A7 and A4.
