I'd use up all my time bank on this one, wondering if he is bluffing me with a flush draw, or if he is loose enough to have KT (possibly suited of spades, which would be a good draw on that flop), or has my ace beat right now. I'd probably fold and still have 2000 chips to play with if he raised me, because there can't be too many hands that I'd be ahead of here that would raise me there after calling a decent bet on the flop and me throwing another good bet on the turn. I am behind to AQ, AJ, KT, 88, JJ, or QQ here, and I can't think of a hand that would raise me here that doesn't have my TPTK beat. So I'd give it up and live to fight another battle.
