200nl defending the button vs a reg

[kabouter]

Villain is a decent regular 19/14/3, quite capable of 2 barreling, I don't put him on 99, simply because he wouldn't play it that fast on a flop like this.
A2 is possible, as is any overpair, could he have had AJ or something? And can we make this call?
