Well you do have a couple of outs to the nuts (A♠ and 9♠), but you're not really beating much here, and good chance someone has either a made flush (you have 7 or 1 out), 15 outs vs 2 pair / set, or 9 outs versus AQ. Trouble is, you're not going to get paid off if you hit, and you could be giving good reverse implied odds
if someone has A♠. You don't have much fold equity by re-raising, because someone who raises generally isn't going anywhere. You also have no made hand, so if there's a naked A♠ out there, you don't even win if you miss. You should probably just fold it.
