[suited aces]

You said the guy is a bit aggressive right -- three bet the flop. If he caps, I probably call down unless a spade shows up. If he calls, I lead the turn. Granted, the turn card here is pretty scary for us. If he raises this turn card, I'd strongly consider folding. If he calls, I probably check/call the river. I'd much prefer bet/folding it, but given that he's a little aggresive, I don't feel like have to face the decision of what to do if he raises the river.
