Haven't played with any of these guys before, SB seems pretty fishy.

SB leads the pot, I think he can do this with any ace so 2 pair is a consideration but not a huge worry for me. I think I'd rather raise here and get some value from my ace. If SB shoves I'd have an annoying decision to make but nothing he's done so far has made me think he would do that. My only real issue here is bet sizing. I'm more hoping to just take the pot now as there are a decent amount of bad turns that can come and this bet commits me to the pot pretty hard. At this point I just figure I'm betting on not folding on most turns.

So the turn adds a flush draw, J9 gets there, A7 and 87 get there. I'm still ahead of lots of hands, KT, QT, most Ax, 98, 97, T9, 99 (though they probably fold flop). If I check here I don't think there's any way that it checks around to see a free river which, honestly, I don't really want anyone else to get. So I think I'm all in here either way. Thoughts?
