Normally, you don't want pocket aces going against a five player field. However, this situation isn't as dire as it first appears. You have the A
in your hand, so you are certain the NFD is not out. Your opponents don't know what you know, and anyone with a subnut flush draw will have to take into consideration that he could be up against the NFD.
You don't have any likely straight draws out there, nor likely two-pair, other than possibly ( K, 9 ). Your main fear here is sets, but sets are
always a possibility anyway.
Here, I'd go $45 into the field, ready to repop it all in if challenged. You aren't gonna fool anyone by checking, as you've already raised pre, and you need to limit your field, and they probably know it. It would be a disaster to let another diamond fall off for free. A lead also looks a lot like an (A, K) that's trying to drive off opponents. Lead out and see if anyone can play back. If one of the shorties shoves, call. He can't really hurt your stack. If there are multiple shoves, consider folding -- that would look too much like a set's already out there. If the other deep stack shoves: caution. You'll just have to assess this vill to see if he'd make that move with a hand that can't beat wired aces.
