Set of Aces with a Turn Decision

[evanski]

5-10 NL on UB, 6 players or so. I have been playing in the game for about an hour and have been very agressive preflop and postflop. I am UTG(1100) and raise to 40 with black aces. Folded around to BB who is smart and tricky and has me covered, who calls. Flop is J72, two hearts. He checks, I bet 80, he checkraises to 220. On two or three previous hands other players have checkraised me after calling my pfr and I have folded. I decide that it is quite likely that I am ahead in this spot, and to call and let the turn card and his action define his hand. I called thinking that if I reraise the flop, Ill either win the pot straight out, be a marginal favorite over a big draw, or get my whole stack in as a big dog. The turn is the ace of hearts. He checks and I, with 500 and change in the pot and 800 in my stack...
