Bet the turn. Call river.
Since the A

, K

, and Q

are accounted for, the J

is the NFD here. However, what could the vill have that includes a J

that he'd play this way? ( J

, T

) is always possible here, but what else? Even if he had that hand, would he fool around with that flop, even though the board paired aces, and he has no reason to believe his flush draw is the nuts at this point? If he shows you an ( A, [Q, 5, 2] ) oh well... If he shows some sort of jack-high hand, make a note. I'd call the river, expecting a chop, or perhaps an over played three aces with a worse kicker.
