Standard is to rr pf. Calling is fine too but with an an aggro image I'm more likely to raise (and stack off if necessary).
As played, I wouldn't raise the flop because I think it makes it far too easy to fold all the hands that are behind here. Given that A

is on the board and K

is in our hand, I'm not worried about draws. I just want to get the max out of weaker aces and smaller big pairs.
