If you're going to play the hand just flat the flop, personally i'd fold and find better spots, don't really want to be playing a big pot OOP on a gutshot which might be no good anyway.
As played I think it was a big spew, you definately do not want to be getting chips in on this flop because you're not beating anything and you're a considerable dog to pretty much anything he could have here.
Edit: my standard line here is to fold on the flop, but I might call if there was a spade on the board and I thought I could get paid off if I hit something.

If I consider making a move on this board, then with something like AdQd etc.
 
I just stoved a few hands and realized that you're even behind most Flush-Draws, your equity can go as low as 32% (Ad7d) and surprisingly, you only have roughly 38-40% equity against a naked flush-draw.
 
This was also surprising to me at first, but after stoving a few more hands, I realized what's going on - any naked flush-draw either has two overcards to your 7 or it's either blocking one of your straight-outs or giving them more straight-outs, both the 4d and the 6d are bad for you if one of them is in your opponent's hands, giving him 59.7% (4d) / 61.8% (6d) equity against your hand..
 
So you're a huge dog against hands like Td4d or Jd6d and it also doesn't help if you're holding AsKs - even AsKs is a 47% dog against the naked flush-draw Qd8d.
 
The reason is simply that you don't have any pair - every naked flush-draw has 15 Outs against you, 9 to make a flush and 6 to make a pair.  With AsKs, you're only slightly ahead against KdXd where X is a 7, 8, 9, T, J or Q.

I like flatting the flop here too. I would like the raise more if the effective stacks were significantly shorter. WIth the stacks this deep the range that he comes over the top of you with has you crushed and I don't think the fold equity you gain from the raise is worthwhile.
