It's hard to find yourself in a 3 suited raggy flop where over playing your AA is possible.
This is exactly how I want my Aces to play out.
Second pair calling me down, you had it even better because his "Ace Kicker" is tainted. You had him drawing to 2 outs.
I do believe you over bet the flop just a bit, but it doesn't seem to have made a difference.
