Too aggressive w/ AA?

[Kyriefurro]

Villain is an unknown. Only played 14 hands with him total.

Relevant stacks:
Hero - 103
SB - 118

Prima 0.50/1 - 6max - 5 players
Hero is in BB w/ A [img]/images/graemlins/diamond.gif[/img],A [img]/images/graemlins/heart.gif[/img]

Preflop: UTG folds, CO folds, Button calls, SB calls, Hero <font color="red"> raises </font> to $6, Button folds, SB calls

($12.50) Flop (2 Players): T [img]/images/graemlins/diamond.gif[/img],K [img]/images/graemlins/diamond.gif[/img],9 [img]/images/graemlins/spade.gif[/img]
SB bets $8, Hero <font color="red"> raises </font> to $25, SB calls.

($62.50) Turn (2 Players): 3 [img]/images/graemlins/club.gif[/img]
SB bets $16, Hero <font color="red"> raises (all-in) </font> to $73.

On the flop I put villain on either a flush draw or a weak K. I did NOT reconsider my read on the turn. But in hind sight, his play looks a little more like a flopped straight.

Thoughts?
